The complex [Cr(3,7diHF)3] ̈ 3H2O (3,7diHF is the monoanion of flavonoid 3,7-dihydroxyflavone) was synthetized and characterized by mass spectrometry, thermogravimetry, UV-Vis and FTIR spectroscopies. The data indicated that the coordination of the chromium(III) ion to the flavonoid increased its thermal stability.

Flavonoid-bearing probes have been designed and synthesized to explore their ability to selectively capture target proteins or biosynthetic enzymes under oxidative activation. A proof-of-concept study using biotinylated (epi)catechin-bearing affinity-based probes herein demonstrates the ability of these probes to capture the LDOX flavonoid enzyme using sodium periodate as the oxidant.

conclusions as a result of the full range uv-vis scanning of the responsible band in the hptlc experiments (200-700 nm), the flavonoid was the most imaginable natural compound. results through the bioassay guided fractionation method, the greatest antibacterial activities were related to the n-hexane extract. it was also revealed that the effective anti-mrsa agent of the assessed plant was a re...

background: due to multiple drug resistance against antimicrobial drugs for treatment of infectious disease, investigations to discovering new antibacterial compounds from natural sources have been designated. objective: according to antimicrobial effects of some capparis species, this study was carried out to evaluate the antimicrobial activity of the extract and fractions of capparis cartilag...

background and objectives:hormozgan province is located in the south of iran, bordering waters of the persian gulf and oman sea. due to the antioxidant potential of plants which might be responsible for their medicinal properties, the antioxidant properties of four medicinal plants of the region were evaluated. methods: the antioxidant properties of chrozophora obliqua, daphne mucronata, salvia...

Estimating flavonoid intake is a first step toward documenting the protective effects of flavonoids against risk of chronic diseases. Although flavonoids are important dietary sources of antioxidants, insufficient data on the comprehensive food composition of flavonoids have delayed the assessment of dietary intake in a population. We aimed to estimate the dietary flavonoid intake in U.S. adult...

Flavonoids are secondary metabolites that are extensively distributed in the plant kingdom and contribute to seed coat color formation in rapeseed. To decipher the genetic networks underlying flavonoid biosynthesis in rapeseed, we constructed a high-density genetic linkage map with 1089 polymorphic loci (including 464 SSR loci, 97 RAPD loci, 451 SRAP loci, and 75 IBP loci) using recombinant inb...

Highbush blueberry (Vaccinium corymbosum) fruits contain substantial quantities of flavonoids, which are implicated in a wide range of health benefits. Although the flavonoid constituents of ripe blueberries are known, the molecular genetics underlying their biosynthesis, localization, and changes that occur during development have not been investigated. Two expressed sequence tag libraries fro...

abstract in this study, the physicochemical quality and antioxidant activities of fruits peel from 6 citrus varieties which commonly consumed in the north of iran were determined. some parameters were measurement such fruit size, peel thickness, residue percentage, peel color indices, total phenolics, total flavonoid, total anthocyanins, total carotenoids, total chlorophyll, ascorbic acid conte...

background: plants and fruits are an essential component of the universe. human beings have used those as medicine from the very beginning of time. according to holy quran, the fruits like grape, date, fig, olive and pomegranate are gifts and heavenly fruits of god. eighteen fruits and plants name have been mentioned in the holy book of moslem. a phytochemical screening of these fruits and plan...
