Absorption, excretion, and distribution of dietary antioxidant betalains in LDLs: potential health effects of betalains in humans. (1/2)

BACKGROUND: Betalains were recently identified as natural antioxidants. However, little is known about their bioavailability from dietary sources. OBJECTIVE: The objective was to evaluate the bioavailability of betalains from dietary sources. DESIGN: The plasma kinetics and urinary excretion of betalains were studied in healthy volunteers (n = 8) after a single ingestion of 500 g cactus pear fruit pulp, which provided 28 and 16 mg indicaxanthin and betanin, respectively. The incorporation of betalains in LDL and the resistance of the particles to ex vivo-induced oxidation was also researched. RESULTS: Betanin and indicaxanthin reached their maximum plasma concentrations 3 h after the fruit meal and declined according to first-order kinetics. The half-life of betanin (0.94 +/- 0.07 h) was shorter than that of indicaxanthin (2.36 +/- 0.17 h). Both compounds had disappeared from plasma by 12 h after intake. The urinary excretion of indicaxanthin and betanin over 12 h represented 76 +/- 3.0% and 3.7 +/- 0.2%, respectively, of the ingested compounds. LDL isolated 3 and 5 h after the fruit meal incorporated betalains at concentrations of 100.5 +/- 11 and 50 +/- 7.2 pmol/mg LDL protein, respectively. In addition, the particles appeared more resistant to ex vivo-induced oxidative injury than did the samples isolated before fruit ingestion (P < 0.05)-the higher the amount of betalains incorporated, the higher the resistance. The concentrations of vitamin E and beta-carotene in LDL did not change significantly after fruit ingestion. CONCLUSION: Our results show that cactus pear fruit is a source of bioavailable betalains and suggest that indicaxanthin and betanin may be involved in the observed protection of LDL against ex vivo-induced oxidative modifications.  (+info)

Antioxidants that inhibit oxidation are stable molecules produced by the host or from the dietary sources.. Free radicals are highly reactive and unstable atoms with a single electron on the outermost ring. To become stable, free radicals intercept or donate an electron from stable atoms, leading to a chain reaction that can not be stopped until all electrons on the outermost ring are paired or inhibited by antioxidants.. Oxidative stress is a result of overexpression of free radicals compared to low levels of antioxidants in the body. Over time, oxidative stress induces protein, lipid, and cellular damage, leading to cells injury and death that facilitate the onset of chronic diseases, including CVD and cancer.. However, free radicals at a moderate level are necessary for the body function, including maintaining the blood vessels in the regulation of relaxation and constriction.. Some diseases associated with free radicals ...

Betalains represent a natural and safe alternative to colour synthetic additives that are used currently in food industry. In addition to the colouring property, betalains are of particular interest because of their importance in health: antimicrobial and antioxidant activity, radio-protective, antiviral, anti-inflammatory and detoxifying effect. This study compares different classics methods of betalains extraction, using water and weak acid solutions from fresh, dried and lyophilized beetroot. The highest content of betanin (20 mg /g) has been obtained from lyophilized beet using 0.5% citric acid and 0.1% ascorbic acid as solvents. In this study temperature, pH, liquid/solid ratio were considered the main factors which influence the performance of extraction process and stability of betanin. The extraction is better at high temperatures (70 C), regardless of the other two parameters. At low temperature it is necessary to increase the liquid/solid ratio and decrease the pH for getting a good ...
The aim of study was investigation the impact of boiling and spontaneous fermentation on profile and content of betalains and antioxidant capacity of red beetroot. Betalains were analyzed by micro-HPLC-TOF-MS/MS method, while antioxidant capacity by three in vitro assays. Red beet products were abounded in betalains, with betanin, isobetanin, betanidin and vulgaxanthin I predominating among twenty two pigments identified. Boiling and fermentation of red beet reduced the content of betalains by 51-61% and 61-88%, respectively, however, this decline was limited when the peel was present. Microbial activity and softening of the matrix induced by the fermentation process led to the release of betalains responsible for strong antioxidant capacity of the juice formed. Generally, the treatment applied maintained and/or lowered antioxidant capacity of red beet materials obtained. Our findings indicate that red beet-derived products are valuable source of betalains, with their profile, content and ...

Many molecules that are considered to be "dietary fiber" are so because humans lack the necessary enzymes to split the glycosidic bond and they reach the large intestine. Many foods contain varying types of dietary fibers, all of which contribute to health in different ways. Dietary fibers make three primary contributions: bulking, viscosity and fermentation.[49] Different fibers have different effects, suggesting that a variety of dietary fibers contribute to overall health. Some fibers contribute through one primary mechanism. For instance, cellulose and wheat bran provide excellent bulking effects, but are minimally fermented. Alternatively, many dietary fibers can contribute to health through more than one of these mechanisms. For instance, psyllium provides bulking as well as viscosity. Bulking fibers can be soluble (i.e., psyllium) or insoluble (i.e., cellulose and hemicellulose). They absorb water and can significantly increase stool weight and regularity. Most bulking fibers are not ...
In soils, it is assumed that larger amounts of phenols are released from decomposing plant litter rather than from throughfall in any natural plant community.[citation needed] Decomposition of dead plant material causes complex organic compounds to be slowly oxidized lignin-like humus or to break down into simpler forms (sugars and amino sugars, aliphatic and phenolic organic acids), which are further transformed into microbial biomass (microbial humus) or are reorganized, and further oxidized, into humic assemblages (fulvic and humic acids), which bind to clay minerals and metal hydroxides.[citation needed] There has been a long debate about the ability of plants to uptake humic substances from their root systems and to metabolize them.[citation needed] There is now a consensus about how humus plays a hormonal role rather than simply a nutritional role in plant physiology.[citation needed] In the soil, soluble phenols face four different fates. They might be degraded and mineralized as a carbon ...
The term carotene (also carotin, from the Latin carota, "carrot"[1][2]) is used for many related unsaturated hydrocarbon substances having the formula C40Hx, which are synthesized by plants but in general cannot be made by animals (with the exception of some aphids and spider mites which acquired the synthesizing genes from fungi).[3] Carotenes are photosynthetic pigments important for photosynthesis. Carotenes contain no oxygen atoms. They absorb ultraviolet, violet, and blue light and scatter orange or red light, and (in low concentrations) yellow light. Carotenes are responsible for the orange colour of the carrot, for which this class of chemicals is named, and for the colours of many other fruits, vegetables and fungi (for example, sweet potatoes, chanterelle and orange cantaloupe melon). Carotenes are also responsible for the orange (but not all of the yellow) colours in dry foliage. They also (in lower concentrations) impart the yellow coloration to milk-fat and butter. Omnivorous animal ...
The highest recorded amount appears to be specifically in the seed coat of black soybean (Glycine max L. Merr.) containing approximately 2 g per 100 g,[27] in purple corn kernels and husks, and in the skins and pulp of black chokeberry (Aronia melanocarpa L.) (see table). Due to critical differences in sample origin, preparation, and extraction methods determining anthocyanin content,[28][29] the values presented in the adjoining table are not directly comparable. Nature, traditional agriculture methods, and plant breeding have produced various uncommon crops containing anthocyanins, including blue- or red-flesh potatoes and purple or red broccoli, cabbage, cauliflower, carrots, and corn. Garden tomatoes have been subjected to a breeding program using introgression lines of genetically modified organisms (but not incorporating them in the final purple tomato) to define the genetic basis of purple coloration in wild species that originally were from Chile and the Galapagos Islands.[30] The ...
Condensed tannins can be characterised by a number of techniques including depolymerisation, asymmetric flow field flow fractionation or small-angle X-ray scattering. DMACA is a dye used for localization of procyanidin compounds in plant histology. The use of the reagent results in blue staining.[11] It can also be used to titrate procyanidins. Total phenols (or antioxidant effect) can be measured using the Folin-Ciocalteu reaction. Results are typically expressed as gallic acid equivalents (GAE). Procyanidins from field beans (Vicia faba)[12] or barley[13] have been estimated using the vanillin-HCl method, resulting in a red color of the test in the presence of catechin or proanthocyanidins. Procyanidins can be titrated using the Procyanidolic Index (also called the Bates-Smith Assay). It is a testing method that measures the change in color when the product is mixed with certain chemicals. The greater the color changes, the higher the PCOs content is. However, the Procyanidolic Index is a ...
True polyphenols from the tannin and other WBSSH types are routinely biosynthesized in the natural sources from which they derive; their 'chemical' syntheses (using standard "bench" organic chemical methods) were somewhat limited until the first decade of the new millennium because these syntheses involve challenging regioselectivity and stereoselectivity issues.[11] Early work focused on the achiral synthesis of phenolic-related components of polyphenols in the late 70's,[12] and the Nelson and Meyers synthesis of the permethyled derivative of the ubiquitous diphenic acid core of ellagitannins in 1994[13] followed by stereoselective synthesis of more complex permethylated structures such as a (+)-tellimagrandin II derivative by Lipshutz and coworkers in the same year,[14] and Itoh and coworker's synthesis of a permethylated pedunculagin with particular attention to axial symmetry issues in 1996.[15] The total synthesis of a fully unmasked polyphenol, that of the ellagitannin tellimagrandin I, ...

Carotenoids are a type of terpenoid (sometimes referred to as isoprenoids), which are hydrocarbons resulting from the combination of several five-carbon isoprene units. Specifically, they are tetraterpenoids, which means they are derived from 8 isoprene units-meaning they typically contain 40 carbon atoms. Structurally they are in the form of a polyene chain that is sometimes terminated by rings. Polyenes are poly-unsaturated organic compounds that contain one or more sequences of alternating double and single carbon-carbon bonds. These double carbon-carbon bonds interact in a process known as conjugation, which results in an overall lower energy state of the molecule. Carotenoids are mainly aliphatic and aliphatic-alicyclic polyenes, with a few aromatic polyenes (McGraw-Hill 2005). (Aromatic compounds contain benzene rings or similar rings of atoms, while aliphatic compounds, such as fat and oil, do not contain aromatic rings; alicyclic are organic compounds that are both aliphatic and cyclic.) ...
