In a recent program to investigate the possible use of vegetable handling and commercialization wastes and residues as a source of potentially bioactive extracts, we have studied cauliflower byproducts. A total of twenty-eight compounds were characterized by HPLC-DAD-MS, of these, twenty-two are produced naturally by the plant. The main compounds found were kaempferol 3-diglucoside-7-glucoside and its combinations with different hydroxycinnamic acids. Moreover, some flavonoids with an unusual high grade of glycosylation have been isolated and tentatively identified for the first time. To our knowledge, the characterization of flavonoids with more than four sugars has not been previously reported. The new products isolated were tentatively identified as kaempferol 3-diglucoside-7-diglucoside, kaempferol 3-triglucoside-7-diglucoside, kaempferol 3-feruloyldiglucoside-7-diglucoside, kaempferol 3-sinapoyltriglucoside-7-glucoside, kaempferol 3-disinapoyltriglucoside-7-glucoside, kaempferol ...

Anti-angiogenesis is probably the most feasible strategy for current chemoprevention of ovarian cancers, given the fact that these early-stage tiny tumors cannot be successfully diagnosed but their continued development desperately depends on the establishment of a new blood vessel network (Bertl et al., 2006; Carmeliet et al., 2000). Tumor-free adults, on the other hand, have virtually zero need for angiogenesis in normal situations (Fotsis et al., 1993; Glade-Bender et al., 2003). Thus our findings about kaempferols anti-angiogenesis effects (Luo et al., 2009) become more relevant in this context. Nevertheless, the previously investigated pathways for kaempferol are not ...

UPLC-based profiling of secondary metabolites | Max Planck Institute of Molecular Plant Physiology
An additional way to validate compounds is to select frequently occurring ions (likely fragments of several different precursor molecules) and extract them from the MS and also the all-ion fragmentation spectra. A very straight forward example can be illustrated for the previously mentioned quercetin- or kaempferol-containing flavonoids. Based on the fact that quercetin- and kaempferol-based flavonoids are decorated with different numbers and kinds of sugars, it is possible to extract the exact m/z 287.05501 for the kaempferol- and the m/z of 303.04993 for the quercetin-containg peaks from the all-ion fragmentation spectra. This directly leads to the distribution of these flavonoids within the chromatogram. If now the retention time information and the isotope-labelling-derived proper mass-shift data are combined, the separated favonoids can be unambiguous annotated.. ...

Human serum albumin (HSA) is a transporting protein that has multiple functions. The binding interaction between HSA and small molecules affects its function and efficacy of small molecules. The present study reports that kaempferol‑7‑O‑α‑L‑rhamnopyranoside (KR) interacts with HSA as indicated by multiple fluorescence spectroscopy and molecular modeling. KR can quench the intrinsic fluorescence of HSA through the formation of a KR‑HSA complex in a static manner. In addition, the binding site is located in subdomain IIA as confirmed by competitive experiments using site‑specific warfarin and ibuprofen, and the driving forces include hydrogen bonds, van der Waals forces and electrostatic interaction derived from a thermodynamic analysis. The formation of KR‑HSA is exothermic and spontaneous. Although there is no hydrophobic interaction around Tyr and Trp residues, the secondary structure of HSA changes through the formation of the KR‑HSA complex. In addition, docking results ...

A Protocol for Flavonols, Kaempferol and Quercetin, Staining in Plant Root Tips -BIO-PROTOCOL
Flavonols are a subclass of flavonoids of the group of plant secondary metabolites. In planta, flavonols play various functions such as antioxidant and natural regulator of auxin polar transport. Many lines of evidence have shown that flavonols also contribute to human health in anti-oxidation, anti-inflammation, and even prevention some types of cancer. Several methods have been utilized to measure flavonols such as high-performance liquid chromatography (HPLC), liquid chromatography-mass spectrometry (LC-MS), and diphenylboric acid-2-aminoethyl ester (DPBA) staining. While HPLC or LC-MS can quantitatively determine the level of flavonols, DPBA staining can provide an in-situ view of flavonols accumulation in the plants. In this protocol, a detailed procedure for staining the flavonols in Arabidopsis root tips is described. Five-day-old Arabidopsis seedlings are soaked in a solution containing DPBA and latterly the flavonols (kaempferol and quercetin) can be observed under a confocal microscope.,
Antioxidant and cytotoxic studies for kaempferol, quercetin and isoquercitrin

The aim of the present study was to investigate a cytotoxic oxidative cell stress related and the antioxidant profile of kaempferol, quercetin, and isoquercitrin. The flavonol compounds were able to act as scavengers of superoxide anion (but not hydrogen peroxide), hypochlorous acid, chloramine and nitric oxide. Although flavonoids are widely described as antioxidants and this activity is generally related to beneficial effects on human health, here we show important cytotoxic actions of three well known flavonoids. They were able to promote hemolysis which one was exacerbated on the presence of hypochlorous acid but not by AAPH radical. Therefore, despite they expected scavenger action over free radicals an oxidants, these compounds could be very lesive to ...

N2 - At a population level there is growing evidence for the beneficial effects of dietary flavonoids on health. However there is extensive heterogeneity in the response to increased intake, which is likely mediated via wide inter-individual variability in flavonoid absorption and metabolism. Flavonoids are extensively metabolized by phase I and II- (which occurs predominantly in the gastrointestinal tract and liver) and colonic microbial- metabolism. A number of factors, including age, gender and genotype may impact on these metabolic processes. In addition food composition and flavonoid source is likely to affect bioavailability and emerging data suggest a critical role for the microbiome. ...

Abstract: Nowadays, much research attention is focused on underutilized berry crops due to the high antioxidant activity of fruits. Black crowberry (L.) represents an important source of flavonols (quercetin, rutin, myricetin, naringenin, naringin, morin, and kaempferol) and anthocyanins. The fruit components could be utilised as natural colourants or as a part of functional foods and, because of the high antioxidant activity, the berries of black crowberry can be used in the treatment of diseases accompanied with inflammation, or as an effective antibacterial and antifungal remedy. Moreover, the reduction of lipid accumulation and total cholesterol as well as an improvement of postprandial hyperglycaemia have been proven. This review summarizes for the first time the main antioxidants (flavonoids) of black crowberry fruits, ...
Flavonoids | ENCOGNITIVE.COM
Flavonoids are a large family of compounds synthesized by plants that have a common chemical structure (1). The basic structure of a flavonoid is shown in figure 1. Flavonoids may be further divided into subclasses (see table 1). Over the past decade, scientists have become increasingly interested in the potential for various dietary flavonoids to explain some of the health benefits associated with fruit and vegetable-rich diets. These potential health benefits are being used to promote the consumption of flavonoid-rich foods, beverages and dietary supplements.

We examined the effects of several agents, including dietary flavonoids, on CYP1A1 expression utilizing a recently developed high-throughput screening system for assessing human cytochrome P450 (CYP) induction. HepG2 cells, stably integrated with regulatory regions of human CYP1A1, were treated with resveratrol, apigenin, curcumin, kaempferol, green tea extract (GTE), (−)-epigallocatechin gallate (EGCG), quercetin, and naringenin. Of these flavonoids, resveratrol produced the greatest increase in CYP1A1-mediated luciferase activity (10-fold), whereas GTE, apigenin, curcumin, and kaempferol produced 2- to 3-fold increases in activity. Compared with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), omeprazole, or benzanthracene, where increases in luciferase activity ranged from 12- to 35-fold, these flavonoids exhibited weak agonist activity. The remaining compounds, EGCG, quercetin, and naringenin, produced negligible effects. Cotreatment of cells with TCDD and GTE, naringenin, and apigenin resulted ...
Molecules | Free Full-Text | A Trinuclear Oxo-Chromium(III) Complex Containing the Natural Flavonoid Primuletin: Synthesis,...
A new trinuclear oxo-centered chromium(III) complex with formula [Cr3O(CH3CO2)6(L)(H2O)2] (L = 5-hydroxyflavone, known as primuletin) was synthetized and characterized by ESI mass spectrometry, thermogravimetry, and 1H-NMR, UV-Vis, and FTIR spectroscopies. In agreement with the experimental results, DFT calculations indicated that the flavonoid ligand is coordinated to one of the three Cr(III) centers in an O,O-bidentate mode through the 5-hydroxy/4-keto groups. In a comparative study involving the uncoordinated primuletin and its corresponding complex, systematic reactions with the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) showed that antiradical activity increases upon complexation.
PLANT BREEDING: June 2005
Recently, it was also found that UV light selectively induces several primary metabolic activities that are directly or indirectly required for flavonoid formation. This implies complex regulation in the different branches of the phenylpropanoid biosynthesis pathway during UV-B stress. Elevated UV-B radiation significantly increased the concentrations of UV-B-absorbing flavonoids, such as quercetin-3-arabinoside, quercetin-3-glucose + glucuronide and kaempferol- 3-rhamnoside, and a few phenolic acids in silver birch leaves. In Arabidopsis thaliana, the transparent testa-4 (tt4) mutant, which has reduced flavonoids and normal levels of sinapate esters, is more sensitive to UV-B than the wild type when grown under high UV-B irradiance. The tt5 and tt6 mutants, which have reduced levels of UV-absorptive leaf flavonoids and the monocyclic sinapic acid ester phenolic compounds, are highly sensitive to the damaging effects of UV-B radiation. These demonstrated that both flavonoids and other phenolic ...

About The Buzz: Dietary Flavonoids Prevent Weight Gain? - Have A Plant
A newly published study, which followed participants for up to 24 years, included 124,000 men and women and began in 1986. In total, over 124,000 people between the ages of 27-65 participated. All study participants self-reported their diet every four (4) years using a food frequency questionnaire. Their flavonoid intake was calculated by how frequently they consumed flavonoid-containing foods. Participants also reported on their lifestyle habits and weight every two (2) years. They were also asked to report any changes in smoking status, physical activity level, hours spent sitting or watching TV, and hours of sleep.. Over each four-year period, men gained 2.2lbs on average and women gained 2.9lbs. Intake of flavonoids was an average of 224 milligrams per day in men and 247 milligrams per day in women. Every additional 10 milligrams of daily intake was associated with 0.16 to 0.23 lbs. less weight gained over four-year periods. A quarter cup of strawberries or cherries contains about 10 mg of ...

Abstract Tiliroside is a glycosidic flavonoid present in many plants species including Helicteres velutina K. Schum (Malvaceae sensu lato), commonly known in Brazil as pitó. This molecule has been shown to have many biological activities, however no study has been carried out to investigate the toxicity of this substance. The present work aimed to evaluate the possible cellular toxicity in silico, in vitro and ex-vivo of the kaempferol-3-O-β-D-(6-E-p-coumaroyl) glucopyranoside (tiliroside), through chemical structure analysis, toxicity assessment and predictive bioactive properties, using human samples for in vitro and ex-vivo tests. The in silico analysis suggests that tiliroside exhibited great absorption index when penetrating biological membranes. In addition, it also displayed considerable potential for cellular protection against free radicals, and anticarcinogenic, antioxidant, antineoplastic, anti-inflammatory, anti-hemorrhagic and antithrombotic activities. The assessment of the ...
