Patterns of evolutionary rate variation among genes of the anthocyanin biosynthetic pathway. (1/731)

The anthocyanin biosynthetic pathway is responsible for the production of anthocyanin pigments in plant tissues and shares a number of enzymes with other biochemical pathways. The six core structural genes of this pathway have been cloned and characterized in two taxonomically diverse plant species (maize and snapdragon). We have recently cloned these genes for a third species, the common morning glory, Ipomoea purpurea. This additional information provides an opportunity to examine patterns of evolution among genes within a single biochemical pathway. We report here that upstream genes in the anthocyanin pathway have evolved substantially more slowly than downstream genes and suggest that this difference in evolutionary rates may be explained by upstream genes being more constrained because they participate in several different biochemical pathways. In addition, regulatory genes associated with the anthocyanin pathway tend to evolve more rapidly than the structural genes they regulate, suggesting that adaptive evolution of flower color may be mediated more by regulatory than by structural genes. Finally, for individual anthocyanin genes, we found an absence of rate heterogeneity among three major angiosperm lineages. This rate constancy contrasts with an accelerated rate of evolution of three CHS-like genes in the Ipomoea lineage, indicating that these three genes have diverged without coordinated adjustment by other pathway genes.  (+info)

Molecular cloning and biochemical characterization of a novel anthocyanin 5-O-glucosyltransferase by mRNA differential display for plant forms regarding anthocyanin. (2/731)

UDP-glucose: anthocyanin 5-O-glucosyltransferase (5-GT) is responsible for the modification of anthocyanins to more stable molecules in complexes for co-pigmentation, supposedly resulting in a purple hue. The cDNA encoding 5-GT was isolated by a differential display applied to two different forms of anthocyanin production in Perilla frutescens var. crispa. Differential display was carried out for mRNA from the leaves of reddish-purple and green forms of P. frutescens, resulting in the isolation of five cDNA clones predominantly expressed in the red form. The cDNA encoded a polypeptide of 460 amino acids, exhibiting a low homology with the sequences of several glucosyltransferases including UDP-glucose: anthocyanidin 3-O-glucosyltransferase. By using this cDNA as the probe, we also isolated a homologous cDNA clone from a petal cDNA library of Verbena hybrida. To identify the biochemical function of the encoded proteins, these cDNAs were expressed in Saccharomyces cerevisiae cells. The recombinant proteins in the yeast extracts catalyzed the conversion of anthocyanidin 3-O-glucosides into the corresponding anthocyanidin 3,5-di-O-glucosides using UDP-glucose as a cofactor, indicating the identity of the cDNAs encoding 5-GT. Several biochemical properties (optimum pH, Km values, and sensitivity to inhibitors) were similar to those reported previously for 5-GTs. Southern blot analysis indicated the presence of two copies of 5-GT genes in the genome of both red and green forms of P. frutescens. The mRNA accumulation of the 5-GT gene was detected in the leaves of the red form but not in those of the green form and was induced by illumination of light, as observed for other structural genes for anthocyanin biosynthesis in P. frutescens.  (+info)

Regulation of mitochondrial KATP channel by redox agents. (3/731)

The ATP-dependent K+ channel (KATP) was purified from the inner mitochondrial membrane and reconstituted into lipid bilayer membranes. KATP activity was inhibited by high concentrations of ATP and ADP, but activated by low concentrations (up to 200 microM) of ADP. p-Diethylaminoethylbenzoate (DEB) acted as a KATP opener: at micromolar concentrations, it reversed inhibition by ATP and ADP and it also prevented KATP rundown. Pelargonidine, extracted from flowers of Pelargonium, reduced spontaneous activity of KATP channels and diminished their potentiation by DEB. Their opposite action on KATP corresponded with their opposite redox properties in reactions with free radicals: DEB behaved as an electron donor, whereas pelargonidine acted as an electron acceptor. We hypothesize that thiol groups on mitoKATP are targets for redox-active ligans.  (+info)

Antimutagenicity of sweetpotato (Ipomoea batatas) roots. (4/731)

Antimutagenicity of the water extracts prepared from the storage roots of four varieties of sweetpotato with different flesh colors was investigated using Salmonella typhimurium TA 98. The extract from the whole roots of the purple-colored Ayamurasaki variety effectively decreased the reverse mutation induced not only by Trp-P-1, Trp-P-2, IQ, B[a]P, and 4-NQO but also by dimethyl sulfoxide extracts of grilled beef. Comparison of the inhibitory activity of the extracts from the normal Ayamurasaki and its anthocyanin-deficient mutant one suggested that the anthocyanin pigment in the flesh decreases the mutagenic activity of the mutagens as heterocyclic amines. Two anthocyanin pigments purified from purple-colored sweet-potato, 3-(6,6'-caffeylferulylsophoroside)-5-glucoside of cyanidin (YGM-3) and peonidin (YGM-6) effectively inhibited the reverse mutation induced by heterocyclic amines, Trp-P-1, Trp-P-2, and IQ in the presence of rat liver microsomal activation systems.  (+info)

Absorption and metabolism of cyanidin 3-O-beta-D-glucoside in rats. (5/731)

We have clarified for the first time how cyanidin 3-O-beta-D-glucoside (C3G), which is a potent antioxidant anthocyanin, is absorbed and metabolized in vivo. Rats were orally administered C3G (0.9 mmol/kg body weight), and C3G rapidly appeared in the plasma. However, the aglycon of C3G (cyanidin; Cy) was not detected, although it was present in the jejunum. Protocatechuic acid (PC), which may be produced by degradation of Cy, was present in the plasma and the concentration was 8-fold higher than that of C3G. These results suggest that plasma PC and C3G may contribute to the antioxidant activity of the plasma. In the liver and kidney, C3G was metabolized to methylated C3G (methyl-C3G), suggesting that C3G and/or methyl-C3G act as antioxidants in the tissues.  (+info)

Hyperoxia-induced changes in antioxidant capacity and the effect of dietary antioxidants. (6/731)

We investigated, by measuring oxygen radical absorbance capacity (ORAC), whether hyperoxia causes alterations in antioxidant status and whether these alterations could be modulated by dietary antioxidants. Rats were fed for 8 wk a control diet or a control diet supplemented with vitamin E (500 IU/kg) or with aqueous extracts (ORAC: 1.36 mmol Trolox equivalents/kg) from blueberries or spinach and then were exposed to air or >99% O2 for 48 h. Although the constituents of the extracts were not extensively characterized, HPLC indicated that blueberry extract was particularly rich in anthocyanins, and the spinach extract did not contain any anthocyanins. The ORAC was determined in samples without proteins [serum treated with perchloric acid (PCA); ORACPCA] and with proteins (ORACtot). Hyperoxia induced a decrease in serum protein concentration, an increase in serum ORACPCA, decreases in lung ORACPCA and ORACtot, and an equilibration of proteins and ORACPCA between serum and pleural effusion. These alterations suggested a redistribution of antioxidants between tissues and an increase in capillary permeability during hyperoxia. Only the blueberry extract was effective in alleviating the hyperoxia-induced redistribution of antioxidants between tissues.  (+info)

Protective effects of dietary nasunin on paraquat-induced oxidative stress in rats. (7/731)

The preventive effects of nasunin (delphinidin-3-[4-p-coumaroyl-rhamnosyl(1-->6)glucosid e]-5-glucoside) on paraquat-induced oxidative stress were determined in rats. Decreased food intake and body weight gain and increased lung weight by feeding the rats a diet containing paraquat were clearly suppressed by supplementing nasunin to the paraquat diet. Paraquat feeding increased the concentration of thiobarbituric acid-reactive substances (TBARS) in liver lipids and the atherogenic index, and decreased the liver triacylglycerol level. These effects were also suppressed by supplementing nasunin to the paraquat diet. In addition, catalase activity in the liver mitochondrial fraction was markedly decreased by feeding the paraquat diet, this decrease being partially suppressed by supplementing the paraquat diet with nasunin. These results suggest that nasunin acted preventively against the oxidative stress in vivo that may have been due to active oxygen species formed through the action of paraquat.  (+info)

ANTHOCYANINLESS2, a homeobox gene affecting anthocyanin distribution and root development in Arabidopsis. (8/731)

The ANTHOCYANINLESS2 (ANL2) gene was isolated from Arabidopsis by using the maize Enhancer-Inhibitor transposon tagging system. Sequencing of the ANL2 gene showed that it encodes a homeodomain protein belonging to the HD-GLABRA2 group. As we report here, this homeobox gene is involved in the accumulation of anthocyanin and in root development. Histological observations of the anl2 mutant revealed that the accumulation of anthocyanin was greatly suppressed in subepidermal cells but only slightly reduced in epidermal cells. Furthermore, the primary roots of the anl2 mutant showed an aberrant cellular organization. We discuss a possible role of ANL2 in the accumulation of anthocyanin and cellular organization of the primary root.  (+info)

The available data demonstrate that even in universal metabolic pathways, some species-specific regulatory features of structural genes are present. For instance, in the anthocyanin biosynthesis pathway (ABP), genes may be regulated by ABP-specific regulatory factors, and their expression levels may be strongly associated with anthocyanin pigmentation, or they may be expressed independently of pigmentation. A dataset of orthologous ABP genes (Chs, Chi, F3h, F3h, Dfr, Ans) from monocot and dicot plant species that have distinct gene regulation patterns and different types of pollination was constructed to test whether these factors affect the evolution of the genes. Using a maximum likelihood approach, we demonstrated that although the whole set of the ABP genes is under purifying selection, with greater selection acting on the upstream genes than on the downstream genes, genes from distinct groups of plant species experienced different strengths of selective pressure. The selective pressure on the
Abstract. Anthocyanins have been studied as potential antimicrobial agents against Helicobacter pylori. We investigated whether the biosynthesis and secretion of cytotoxin-associated protein A (CagA) and vacuolating cytotoxin A (VacA) could be suppressed by anthocyanin treatment in vitro. H. pylori reference strain 60190 (CagA+/VacA+) was used in this study to investigate the inhibitory effects of anthocyanins; cyanidin 3-O-glucoside (C3G), peonidin 3-O-glucoside (Peo3G), pelargonidin 3-O-glucoside (Pel3G), and malvidin 3-O-glucoside (M3G) on expression and secretion of H. pylori toxins. Anthocyanins were added to bacterial cultures and Western blotting was used to determine secretion of CagA and VacA. Among them, we found that C3G inhibited secretion of CagA and VacA resulting in intracellular accumulation of CagA and VacA. C3G had no effect on cagA and vacA expression but suppressed secA transcription. As SecA is involved in translocation of bacterial proteins, the down-regulation of secA ...
Characterization and quantification of anthocyanins in selected tea cultivars processed into black (aerated) and green (unaerated) tea products was carried out in this study. The anthocyanins were extracted from tea products processed from a number of newly bred purple leaf coloured Kenyan tea cultivars (Camellia sinensis) using acidified methanol/HCl (99:1 v/v). Extracted anthocyanins were purified by C 18 solid phase extraction (SPE) catridges and characterised by HPLC-UV-Visible. They were identified according to their HPLC retention times, elution order and comparison with authentic standards that were available. Total monomeric anthocyanins were determined by the pH-differential method. Although the tea cultivars gave different yields of anthocyanins, the unaerated (green) teas had significantly (p 6 0.05) higher anthocyanin content than the aerated (black) teas. This was attributed to the degradation of anthocyanins by polyphenol oxidase products (catechin O-quinones) formed during the ...
Anthocyanins are naturally occurring polyphenols that impart bright color to fruits, vegetables and plants. In this study, the extraction of anthocyanins from freeze-dried fruit skin of downy rose-myrtle (Rhodomyrtus tomentosa (Ait.) Hassk var. Gangren) was optimized using response surface methodology (RSM). Using 60% ethanol containing 0.1% (v/v) hydrochloric acid as extraction solvent, the optimal conditions for maximum yields of anthocyanin (4.358 ± 0.045 mg/g) were 15.7:1 (v/w) liquid to solid ratio, 64.38 °C with a 116.88 min extraction time. The results showed good fits with the proposed model for the anthocyanin extraction (R2 = 0.9944). Furthermore, the results of high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) analysis of the anthocyanins extracted from the fruit skin of downy rose-myrtle revealed the presence of five anthocyanin components, which were tentatively identified as delphinidin-3-glucoside, cyanidin-3-glucoside, peonidin-3-glucoside,
The TRANSPARENT TESTA GLABRA1 (TTG1) locus controls many apparently unrelated characters of Arabidopsis (catalogued by Koornneef, 1981), several of which appear to be confined to the epidermal cell layer of different tissues. ttg1 mutants have a glabrous phenotype, possessing none of the leaf or stem hairs (trichomes) that normally are derived from the meristematic L1 cell layer. Purple anthocyanin pigments are absent from the ttg1 seed coat, causing the transparent testa phenotype in which the yellow cotyledons are visible through the testa. In wild-type plants, anthocyanins are present in the hypocotyl of seedlings and in the stem and leaves of plants as they age, and they are inducible by many forms of stress, including high light, poor nutrients, or water stress. ttg1 mutants completely lack anthocyanins in the epidermis and in subepidermal layers of leaves and stems. Mucilage normally found in the cell wall of the seed coat is absent in ttg1 mutants. Seeds of ttg1 plants do not require ...
Anthocyanin from the red-color-melinjo peels could be isolated using a polar solvent (ethanol) [ermiziar, 2010]. The amount of hydrocarbons in the structure of anthocyanin might cause that anthocyanin could be isolated using a non polar solvent. The purpose of research is to isolate anthocyanin using non polar solvents (hexane and petroleum ether) with maceration steps for 24 hours and separate solvents using rotary evaporator equipment. The stability of anthocyanin could be observed every week (1,2,3 and 4 weeks) in various environmental conditions (with or without light in refrigerator and open or closed storage). The characterization of anthocyanin was analyzed with visual (physic photo) and or using equipments such as Fourier Transform Infrared Spectroscopy (FTIR) for determining functional groups, Ultraviolet-Visible Spectroscopy (UV/Vis) with 500-550 nm wavelengths for deciding absorption of anthocyanin and atomic absorption spectroscopy (AAS) for analyzing Fe element. The result showed ...
Studies have shown that the consumption of anthocyanins has positive effects on human health. They act as an anti-oxidant, anti-allergic, anti-microbial, anti-inflammatory, and help improve microcirculation of the body. Anthocyanins are known to expedite the process of metabolism of cholesterols and blood sugar. Further, anthocyanins fight oxidative stress, a process known to play a crucial role in escalating heart diseases. Consumption of anthocyanins is also known to reduce the level of obesity in humans.. The rising awareness regarding these factors in the past few years has led to a significant rise in the global consumption of anthocyanins and is expected to be a key driver of the market over the forecast period as well. Additionally, the global anthocyanins market is expected to be driven owing to the steady growth witnessed by the market across developing countries such as India, Brazil, China, Indonesia, and Argentina, in the past few years.. Difficulty in Processing Natural Food Colors ...
In the last decade, there has been an increased interest in anthocyanin-based research with a growing need to accurately measure anthocyanin intake in population studies. Anthocyanin content in foods is known to vary across regions due to climate, soil content and harvesting practices. To accurately measure nutrient intake in population studies, food composition databases tailored to specific regions need to be developed. The aim of this study was to describe the first stage development of an Australian anthocyanin food composition database focusing on fruit and vegetables. A systematic literature search found analytical data on the anthocyanin content of five fruits and two vegetables (purple dragon carrot and red cabbage) out of the total plant-based food category (58 individual fruits and 62 vegetables). In addition, values were found for ten Australian native fruits, of which 9 are not included in the Australian database. Development of an anthocyanin food composition database relies on the
In the present work, a new purification method of anthocyanins with o-dihydroxy arrangement is proposed. This method is based on a ligand-exchange mechanism, using a cationic exchange resin loaded with metallic ions in order to increase the affinity of the resin to the anthocyanin(s) with o-dihydroxy arrangement. This method was used to purify the main anthocyanin (cyanidin-3-glucoside; Cy-3-glc) from the anthocyanic methanolic extract of blue corn. The best sorption result was using Fe(III) in its ion form. The purification procedure begins with the formation of a metal-anthocyanin complex (Cy-3-glc-Fe) which was optimal at pH 5, followed by a NaOH 0.1?M elution process in order to eliminate anthocyanins without o-dihydroxy arrangement, sugars, and organic acids. Finally, the pure anthocyanin is obtained by adding HCl 0.1?M which breaks the metal-anthocyanin complex. ...

Our objective was to develop a robust system for anthocyanin-based color intensification, with high-encapsulation capacity and improved stability of the encapsulated natural colorant. Catechin was used to modulate the copigmentation and encapsulation of anthocyanins in counter-ionic polyelectrolyte complexes (PECs) composed of chondroitin sulfate and chitosan. Results showed that catechin copigmentation significantly intensified red color of formulations both with and without encapsulation in PECs and improved the anthocyanin encapsulation efficiency by forming additional dense network through hydrogen bonding. A series of stability assays revealed that anthocyanin stabilizing effect of system depended on the formulated pH and adding order of catechin. The strongest retaining capacity of anthocyanin was observed when catechin was copigmented with anthocyanin directly in PECs at pH 3.3, while the coated layer of catechin covered on PECs would be more effective at pH 4.0 and 5.0. Furthermore, we
Seven red raspberry (Rubus Ideaus L.) samples from Oregon, Washington, British Columbia and New Zealand were processed into juice. These, along with three juice samples supplied from West Germany were analyzed by high performance liquid chromatography, (HPLC), for nonvolatile acid, sugar, anthocyanin and anthocyanidin composition. In order to quantitate the compounds of interest, particular attention was given to selection and improvement of HPLC analytical procedures. Adequate resolution of malic acid from isocitric by reverse phase C-18 chromatographic media was achieved using a two column system. The more uniform response of analytes to refractive index detection allowed for quantitation of isocitric acid. Sugar analysis based on a crosslinked cation exchange resin required removal of the acids from the juice via anion exchange. Resolution of anthocyanin pigments was achieved using as organic modifier 15% acetic acid. Acetic acid (15%) demonstrated high selectivity in resolving pigments with ...
Abaxially anthocyanic leaves of deeply-shaded understorey plants play important ecological significance for the environmental adaption. In contrast to the transient pigmentation in other plants, anthocyanins are permanently presented in these abaxially red leaves, however, the mechanism for the pigment maintenance remains unclear. In the present study, we investigated phenolic metabolites that may affect pigment stability and degradation in Excoecaria cochinchinensis (a bush of permanently abaxial-red leaves), via a comparison with Osmanthus fragrans (a bush of transiently red leaves). High levels of galloylated anthocyanins were identified in the Excoecaria but not in the Osmanthus plants. The galloylated anthocyanin showed slightly higher stability than two non-galloylated anthocyanins, while all the 3 pigments were rapidly degraded by peroxidase (POD) in vitro. High levels of hydrolysable tannins [mainly galloylglucoses/ellagitannins (GGs/ETs)] were identified in Excoecaria but none in Osmanthus. GGs
7 Life Changing Reasons To Eat More Anthocyanins + Top Foods:. By now, were all aware of the incredible health benefits of eating fruits and vegetables. However, many people dont realize exactly why these fresh foods are so amazing.. While they boast an array of health benefits - including vitamins, minerals and fiber - fruits and vegetables also contain some special compounds that can help protect us from an ever-growing list of diseases.. One group of such of compounds is the anthocyanins - a type of flavonoid. You may already be familiar with flavonoids - a family of powerful antioxidants - from reading up on the healthful properties of green tea, cocoa and red wine.. But anthocyanins deserve special recognition for their protective properties. So powerful are the anthocyanins that tests have shown they can yield twice the antioxidant power of vitamin C!. Another great benefit of anthocyanins is that they are so easily recognized! Just looking at your plate is enough to tell if your food ...
Anthocyanins are synthesized directly from anthocyanidins by glycosylation (adding of a sugar to a protein) at the 3 and 5 positions of the C ring and are accumulated in the berry skins from veraison until full maturity. After synthesis in the cytosol (fluid portion of the cell cytoplasm), anthocyanins are transported into the vacuole (cell organelle responsible for a number of functions including nutrient storage) where they are stored as colored coalescences called anthocyanic vascular inclusions (Flamini, et al ...

The level of pigment in the F2s was a surprise as I hadnt noted any anthocyanin expression in the parent varieties. After seeing the F2s, I re-examined some "Tiny Tim" plants grown this year and found they did have anthocyanin expression. The fruit show a level of anthocyanin production comparable to the high-fruit-pigment F2s (image #5), but the small size of the fruit made it hard to notice. The F1 showed a pigment level like the medium-fruit-pigment F2s, suggesting it is a single trait with partial dominance. The color of the calyx and leaf/stem was comparable to the F2 plants with the middle level of pigment for each feature. Looking into the lineage of "Tiny Tim" suggests the middle-pigment trait was contributed from S. pimpinellifolium, used in the breeding to contribute small fruit size to "Tiny Tim". As anthocyanin pigments on the shoulder is common in many wild tomato relatives, I suspect the fruit trait also came from S. pimpinellifolium. ...

The cross talk among hydrogen peroxide (H2O2) nitric oxide (NO) and UV RESISTANCE LOCUS8 (UVR8) in UV-B-induced anthocyanin accumulation in the hypocotyls of radish sprouts was investigated. H2O2-induced anthocyanin accumulation and expression were significantly suppressed by co-treatment with 2-phenyl-4 4 5 5 (PTIO a NO scavenger) which was parallel with the expression of anthocyanin biosynthesis-related transcription factors and structural genes. All these results demonstrate that both H2O2 and NO are involved in UV-B-induced anthocyanin accumulation and there is a crosstalk between them as well as a classical UVR8 pathway. Anthocyanins are plant secondary metabolites synthesized through the flavonoid pathway generating the characteristic reddish bluish and purple hues which contribute to flower pigmentation attraction of pollinators and seed dispersers1. In addition they are also important as antioxidant molecules to protect plant cells against damage by reactive oxygen species (ROS)2 ...
The adsorption of ochratoxin A (OTA) by yeasts is a promising approach for the decontamination of musts and wines, but some potential competitive or interactive phenomena between mycotoxin, yeast cells, and anthocyanins might modify the intensity of the phenomenon. The aim of this study was to examine OTA adsorption by two strains of Saccharomyces cerevisiae (the wild strain W13, and the commercial isolate BM45), previously inactivated by heat, and a yeast cell wall preparation. Experiments were conducted using Nero di Troia red wine contaminated with 2 μg/L OTA and supplemented with yeast biomass (20 g/L). The samples were analyzed periodically to assess mycotoxin concentration, chromatic characteristics, and total anthocyanins over 84 days of aging. Yeast cell walls revealed the highest OTA-adsorption in comparison to thermally-inactivated cells (50% vs. 43% toxin reduction), whilst no significant differences were found for the amount of adsorbed anthocyanins in OTA-contaminated and control wines.

The lability of anthocyanins and flavonols extracted from grape (Vitis vinifera L.) skin with commonly used extraction solvents was examined. Results indicate that both anthocyanins and flavonol glycosides are unstable in even mildly acidic extraction solvents and highly labile in 1% hydrochloric acid in methanol, the most commonly used extraction solvent. While lability of anthocyanins has previously been reported, this is the first report of flavonol glycoside stability in these solvents. As a result of these observations, an extraction protocol was developed that maximized anthocyanin (malvidin-3-O-glucoside, malvidin-3-O-acetylglucoside, and malvidin-3-O-p-coumaroylglucoside) and flavonol (quercetin-3-O-glucoside and quercetin-3-O-glucuronide) extraction while minimizing degradation in the time between extraction and HPLC analysis. A range of acidified methanol solvents including hydrochloric, formic, acetic, citric, and maleic acids were tested together with acidulated ethanol and several ...
Drug Class and Mechanism. Acai is a rich source of anthocyanins and other phenolics. Anthocyanins are compounds that have potent antioxidant activity, allowing for the neutralization of potentially harmful free radicals. By neutralizing these free radicals, anthocyanins from Acai may serve to maintain the healthy function of numerous systems and organs. Some of the anthocyanins that have been found in Acai include cyanidin-3-glucoside and cyanidin-3-glucoside-coumarate. Other phenolics include catechin and epi-catechin (the same compounds in green tea), quercetin derivatives and other flavonoids. It is likely that the synergistic effects of these compounds as present in acai fruit are responsible for its potent antioxidant activities ...
Several polyphenolic compounds and their conjugated metabolites were detected and quantified in plasma samples of older adults consuming freeze-dried strawberry powder for 90 days. Parent anthocyanins, including the primary glucuronide conjugate of pelargonidin, three urolithin derivatives and fifteen phenolic acid metabolites were quantified. Important findings included: evidence for persistence of anthocyanins and some phenolic acid metabolites in circulation with chronic strawberry intake, enhancement in 2 h anthocyanin/metabolite and phenolic acids (4-hydroxybenzaldehyde, trans-cinnamic acid, hippuric acid and p-coumaric acid) concentrations after a strawberry drink supplementation, and urolithin metabolites were observed only in 68% of subjects with large inter individual variability. In acute pharmacokinetic studies conducted by our group22,23 and others,15 strawberry anthocyanins peaked within 1-3 hours and were back to baseline concentrations by 8-10 hours after consumption.22 However, ...
Background & Aims: Anthocyanins may have beneficial effects on lipid metabolism and inflammation and are demonstrated to have hepatoprotective properties in models of restraint-stressand chemically-induced liver damage. However, their potential to protect against non-alcoholic steatohepatitis (NASH) under conditions relevant for human pathogenesis remains unclear. Therefore, we studied the effects of the standardised anthocyanin-rich extract Mirtoselect on diet-induced NASH in a translational model of disease..

Carnation variety 29952 flowers have a novel flower colour due to the biosynthesis of the anthocyanin pigment delphinidin. This pigment is not produced in non-transgenic carnation. The genes introduced into the transgenic carnation lines included a functional dihydroflavonol reductase encoding gene (dfr) from petunia and a gene encoding the enzyme flavonoid 3, 5-hydroxylase (F35H). Expression of the F35H encoding gene allows for the production of blue coloured delphinidin anthocyanin pigments ...
Dihydroflavonols are substrates for the biosynthesis of the coloured anthocyanin pigments, which are produced in three steps: firstly a reduction, catalysed by the enzyme dihydroflavonol 4-reductase (DFR); secondly the production of colourless anthocyanidin through the action of anthocyanidin synthase and thirdly addition of a glucose residue to produce a coloured anthocyanin molecule ...
Dr. Sarah Forester. According to the American Cancer Society, colon cancer is the third most common type of cancer in the United States for both men and women. Consumption of a healthy diet, including fruits and vegetables, may help prevent this disease. Anthocyanins are a class of phenolic compounds that contribute to the color of foods such as strawberries, pomegranates, and grapes. These compounds have been shown to reduce the incidence of colon cancer, yet they are heavily metabolized in the body, limiting their anti-cancer activities. Specifically, anthocyanins are methylated by catechol-O-methyltransferase (COMT), transforming them into less bioactive compounds. COMT activity can be inhibited by a drug called entacapone. This drug is used to improve the symptoms of Parkinsons disease patients, yet it could also be used to improve the anti-cancer effects of food-derived anthocyanins. The purpose of this project is to test if entacapone can enhance intracellular levels and anti-cancer ...

Anthocyanins are the largest class of pigments in the plant kingdom. Frequently found in red, purple and blue plants, they are researched for their health benefits, which include anti-oxidant and anti-inflammatory effects.
The pigments that give plant foods their vibrant colors are of value to the plants themselves, as well as to those who consume them. These colorful fruit and vegetable pigments also serve to attract feeding animals who later help distribute the plants seeds.. Plant pigments have long been of interest to food chemists who have studied their contributions to the visual appeal of foods. In recent years, there also has been an explosion of interest in the health potentials of the pigments that are responsible for food colors.. There are several types of pigments in foods. One group is the "anthocyanins", a term derived from the Greek words for "flower" and "blue". Anthocyanins are present in many fruits including cherries, blueberries, blackberries, and cranberries. They also are found in colored grains such as purple corn, red rice, black rice, purple carrots and blue potatoes. One of the richest sources of anthocyanins is the chokecherry. Black rice, which has a purple-black bran, also has very ...

There are lots of misnomers in the world of plant food colors. "Red" cabbage and onions, and lettuce definitely look purple, purple potatoes can look blue. (And cooked blueberries are definitely purple.) Lots of "black" fruit and grains turn out purple: black rice, black mission figs, black grapes, blackberries. Perhaps I ought to forgive whoever named all of these plants, though. Purple is very much in the same family of the red/blue anthocyanins. And that means purple plant foods get their coloring from anthocyanins, which are very shifty, pH sensitive colorants. So most purple plant foods have the same properties for the cook as those blue and red anthocyanins: stable when exposed to heat, but sensitive to pH. It is worth noting that many anthocyanin-rich purple foods often also have a high concentration of tannins. Tannins produce the sensation (rather than a taste) of astringency. Think of the dry, puckering sensation you get from a badly made cup of tea, and you know what astringency is. ...

Anthocyanin. Jack Sullivan. Keywords: chemistry: pigmentation.. Introduction. The red coloration found in carnivorous plants is caused by plant pigments known as anthocyanins. Because of the interest in pigment-free forms of certain carnivorous plants, Barry Rice asked me to write a brief summary of the biochemistry of these pigments. While somewhat technical, it is a fascinating topic. If you are interested in learning more about this topic and how it is related to the biology and evolution of these plants, read on.. Biology. Anthocyanins are members of a class of nearly universal, water-soluble, terrestrial plant pigments that can be classified chemically as both flavonoid (related to flavone/isoflavone, C15H10O2) and phenolic (related to phenol, C6H5OH). They are found in most land plants, with the exceptions of the cacti and the group containing the beet. They contribute colors to flowers and other plant parts ranging from shades of red through crimson and blue to purple, including yellow ...

Cherries protect against oxidative stress:. Cherries range in color from yellow and pink to bright red to deep, dark red. The colors of sweet and sour cherries come from their rich supply of anthocyanins, including chlorogenic acid, quercetin, and kaempferol.3,4 Regarding antioxidant content, cherries are some of the highest ORAC (oxygen radical absorbance capacity) foods in existence - the ORAC score of sweet cherries ranks just as high as strawberries (though not quite as high as blueberries).5 Anthocyanins protect the body against oxidative damage in a number of ways: they scavenge free radicals directly, bind to DNA to protect it from oxidative damage, and activate detoxification and antioxidant enzyme systems in the body. Cherry anthocyanins have been shown to protect blood vessels and brain cells against oxidative stress, implying that cherry consumption may help to prevent atherosclerotic plaque formation and neurodegenerative diseases like dementia.3,6 Cherry anthocyanins also slow the ...

In inflammation, bacterial products and proinflammatory cytokines induce the formation of large amounts of nitric oxide (NO) by inducible nitric oxide synthase (iNOS), and compounds that inhibit NO production have anti-inflammatory effects. In the present study, we systematically investigated the effects of 36 naturally occurring flavonoids and related compounds on NO production in macrophages exposed to an inflammatory stimulus (lipopolysaccharide, LPS), and evaluated the mechanisms of action of the effective compounds. Flavone, the isoflavones daidzein and genistein, the flavonols isorhamnetin, kaempferol and quercetin, the flavanone naringenin, and the anthocyanin pelargonidin inhibited iNOS protein and mRNA expression and also NO production in a dose-dependent manner. All eight active compounds inhibited the activation of nuclear factor ...

The Dissociation (Ds) mutant, Bz-wm, of the maize bronze-1 (bz) locus conditions a leaky phenotype. Plants carrying this mutant allele synthesize a low amount of an altered Bz gene product, which leads to reduced anthocyanin pigmentation in the seed. The molecular analysis reported here shows that the Bz-wm mutant has a 406-bp Ds1 insertion located 63 bp 5 to the start of Bz transcription. Furthermore, the Bz-wm allele contains three additional base pairs within the second exon, relative to the wild-type Bz allele. These additional nucleotides are believed to be derived from the 8-bp target site duplication created by an Activator (Ac) element in a previous allele in the series. The biochemical and molecular analyses of Bz-wm and revertants of Bz-wm indicate that the three additional nucleotides are responsible for the altered enzyme stability, while the Ds1 element affects the steady-state level of Bz-specific protein and RNA. Since the two mutations present in the Bz-wm mutant were each ...

Flowers produce a variety of biological pigments as sources of color. Carotenoids, such as beta-carotene and xanthophylls, are produced and stored in chromoplasts-the orange organelles seen inside these petal cells. The red, purple, and pink anthocyanins are produced by petal cells and stored in the vacuole, which takes up most of the cells volume. Together, the orange chromoplasts and hot pink anthocyanins make this Calibrachoa flower, a relative of petunias, look red to us and to pollinating animals. The cone shaped cells of the epidermis at the top of the image are responsible for the velvety look of the petals and may provide additional visual and tactile signals to pollinators-like landing on a soft red carpet..

Major flavonol glycosides, 3-O-(2"-O-alpha-rhamnosyl-6"-O-malonyl)-beta-glucoside, 3-O-(6"-O-alpha-rhamnosyl-6"-O-malonyl)-beta-glucoside and 3-O-(2",6"-di-O-alpha-rhamnosyl)-beta-glucoside of kaemferol, quercetin and myricetin were isolated from the petals (4,5). The flowers also contain minor delphinidin glycosides, 3-O-b-glucoside, 3-O-(2"-O-a-rahmnosyl)-b-glucoside, 3-O-(2"-O-a-rahmnosyl-6"-O-malonyl)-b-glucoside of delphinidin (4). Eight anthocyanins (ternatins C1,C2,C3,C4,C5 and D3, and preternatins A3 and C4) were also isolated from the flowers (5), (6). Six ternatins from the flowers were partly characterized as highly acylated dephinidin derivatives (7). Deacylternatin was determined as delphinidin 3,3,5-tri-O-b-D-glucopyranoside (7). White petals do not contain anthocyanins (8). There are low levels of condensed tannins (0-2.48 mg catechin/g) and protein precipitable polyphenols (0.16-0.77 mg tannic acid/g) in the raw mature seeds (9 ...
The pigments in leaves are chlorophyll, carotenoids, and anthocyanins. Chlorophyll is the green pigment that is necessary for photosynthesis (making sugar from CO₂ and water using sunlight) and are found in chloroplasts of leaf cells. Carotenoids produce yellow, orange and brown colors in fruits and vegetables as well as in leaves, and anthocyanins give color to fruits such as cranberries, red apples, blueberries, strawberrries, and plums. Chlorophyll and carotenoids are found in chloroplasts throughout the growing season. When chlorophyll fades out as nights get long and temperatures go down, carotenoids get a chance to shine. Most anthocyanins, which are present in the watery liquid of plant cells are produced in fall in response to light and excess sugars that are trapped in leaves when the flow of fluids is cut off by the accumulation of cells at the base of the stem holding leaves to twigs. They too can be seen when green chlorophyll is no longer produced. That layer of cells I mentioned ...
ABSTRACT. Extraction of phenolic compounds from bean seed coats by acetic acid was evaluated and compared to conventional extraction with 80% methanol. Total phenols, flavonoids and free radical scavenging capacity were determined by colorimetric methods. Furthermore, qualitative flavonoid characterization was performed via HPLC diode array. The acetic acid extract contained 73.4 ± 7 mg/g of sample expressed as gallic acid equivalents (GAE), and 41.3 ± 4 mg/g as catechin equivalents (CE). The acetic acid extract (at 1 mg/mL) showed over 89% efficiency to scavenge the 1,1 diphenyl- 2-picrylhydrazil (DPPH) radical (EC50 = 6.13 mg extract/mg standard). Gallic acid, delphinidin-3-glycoside, petunidinglycoside, petunidin, malvidin-3-glycoside, myricetin-glycoside, quercitin-glycoside, saponin (β-g), and 3-hydroxy-5, 7-megastigmadien-9-one were identified in both extracts. Additionally, kaempferol-3-glycoside was found in the acetic acid extract. Sequential acetic acid extractions indicated that ...
The aim of this study was to determine the effects of processing of sour cherry juices on quality parameters (soluble dry matter, pH value, total acidity), color parameters and biologically active compounds. From industrial juice production factory, fresh fruit at the beginning, juices after presses, juices after filtration and concentrated juices were sampled during the processing. Two varieties, Maraska and Oblaĉinska, were investigated. Sensory analysis of concentrated juices was also conducted. According to results expressed on fresh sample values, concentrations of phenols and anthocyanins as well as antioxidant capacity, increased in order: fruit, juice after presses, juice after filtration and concentrated juice, for both Maraska and Oblaĉinska. When expressed on a dry weight, the trend is the same for all parameters, except for anthocyanins which reduced during concentration. Reduction of anthocyanins was lesser in Marasca juice in relation to Oblaĉinska juice. Given the variety, all ...

Slight changes in pH have a significant effect on the color of anthocynin since the acidity affects the ration between the various forms of the pigment and are responsible for the color the fruit has. Acidic ph gives a red color, more basic pH a blue and very basic pH makes it colorless. The molecule that changes with the pH is called cyanidin. Remember: A cyanidin with attached sugars is called an anthocyanin ...

Eat the Rainbow". Its silly. Its cheesy. But its also a good reminder.. We should be eating lots of different kinds and colors of veggies every day.. Not only does this help diversify our gut bacteria, but different colors provide out bodies with different nutrients and antioxidants.. Eating a variety of kinds and colors of vegetables helps from the inside out- youll be looking and feeling your best when you "eat the rainbow.". But dont just take my word for it, heres a quick rundown on the different different colors and the myriad of ways they keep you in tip top shape:. Blue/Purple: These veggies get their dark hues from the antioxidant Anthocyanin. In fact, the darker the color, the more anthocyanins a food has (This is also a good indication your veggie is ripe and ready to eat!) Purple fruits and vegetables are good for your heart and may protect against cancer.. ...

We examined the regulation and localization of the RNS1 and RNS2 proteins, as well as the effects of diminishing their levels via antisense. First, use of antibodies that detect RNS1 and RNS2 individually showed that RNS1 and RNS2 protein levels increase dramatically during Pi starvation and coordinate with increases previously reported for mRNA accumulation (Taylor et al., 1993; Bariola et al., 1994). These same antibodies demonstrated that RNS1 and RNS2 have different subcellular locations, with RNS1 located extracellularly and RNS2 located intracellularly. Finally, although RNS1 and RNS2 are closely related proteins, diminishing the level of either of these RNases individually leads to elevated levels of anthocyanins in Arabidopsis.. Obtaining antisera that recognize individual RNS proteins is an important first step in dissecting the contributions of individual RNase activities to the physiology of Arabidopsis. Although the deduced amino acid sequences of RNS1 and RNS2 are 37% identical ...
Despite the cold nights the sun is shining at the farm, "Purple Sun" that is- a striking deep purple skinned potato with a gold flesh. Purple potatoes can be traced back thousands of years to their native Peru, where these violet colored gems were reserved for the Incan kings. They must have been on to something, because we now know these potatoes have exceptional health benefits, and they are even being cross bred to amplify their nutritional value. The purple spuds pigment is courtesy of the antioxidant anthocyanin, which is responsible for the purple and blue color of fruits and veggies and for immune boosting, memory loss protection, anti-cancer and heart protection benefits. The Purple Sun potato has high levels of vitamin C- 40% of RDA per serving. And its super tasty- excellent for roasting and baking! I knew we ate like kings and queens - this just confirms it!. ...

7 Eyesight Anthocyanins might also improve eyesight. Thirty-six people were examined for their ability to adapt to the light and dark both before and after the oral administration of bilberry anthocyanins. For several hours after the administration of the anthocyanins, their eyesight was improved significantly, although the effect declined within 24 h [51]. Anthocyanoside extracts of Vaccinium Myrtillus improved night vision [52]. Healthy human subjects were tested for dark adaptation, video display terminal (VDT) work-induced transient refractive alteration, and subjective asthenopia symptoms (visual fatigue) after intaking the black currant anthocyanosides (BCAs). This has given rise to what is now popularly termed the "French paradox". The cardioprotective effect might be attributed to the antioxidants present in the polyphenol fractions of the red wines. The grapes are rich in diverse antioxidants such as resveratrol, catechin, epicatechin and proanthocyanidins. Interestingly, among these ...

Also known as Vaccinium myrtillus, European blueberry, Airelle, Bilberry Fruit, Bilberry Leaf, Black Whortles, Bleaberry, Blueberry, Burren Myrtle, Dwarf Bilberry, Dyeberry, Huckleberry, Hurtleberry, Myrtilli Fructus, Trackleberry, Whortleberry, Wineberry. Introduction Also known as "Black Hearts" according to Thomas Hardy in his 1878 novel The Return of the Native, the European bilberry bush is a close relative of American blueberries, cranberries, and huckleberries. It flourishes in damp acidic soil throughout temperate and subarctic regions of the world. The bilberry has a long history of medicinal use. Hildegard of Bingen wrote 900 years ago to recommend the use of bilberries to treat amenorrhea. Renaissance physicians used bilberries to treat conditions ranging from kidney stones to typhoid fever. Traditionally, strong decoctions have also been used as an astringent for treatment of diarrhea and dysentery. The English used it as a dye for wool due to its wonderful dark blue/purple coloring. ...
Although often called huckleberry, the bilberry is more nearly related to the cranberry. Vaccinium myrtillus has been used for nearly 1,000 years in traditional European medicine. Bilberry fruits have been used in the traditional Austrian medicine internally (directly or as tea or liqueur) for treatment of disorders of the gastrointestinal tract and diabetes. Herbal supplements of V. myrtillus (bilberry) on the market are used for circulatory problems, as vision aids, and to treat diarrhea and other conditions.. Bilberry is a well-known folk remedy for poor vision, especially for people who suffer from "night blindness," that is, they have difficulty seeing in the dark. In fact, bilberry jam was given to Royal Air Force pilots who flew nighttime missions during World War II. It works by accelerating the regeneration of retinol purple, commonly known as visual purple, a substance that is required for good eyesight. European medical journals are filled with studies confirming bilberrys positive ...
