Every year lots of black tea (Camellia sinensis (L.) Kuntze) residue will produce in the factories. These residue are unusable whereas the bio active compounds can be extracted and used in the drag and food industries. Due to mentioned problems, this project was conducted years 2011 - 2012 with the aim to make a study on consecutive isolation of all bio active compounds from tea residu...

The present manuscript reviews the findings of different research studies that evaluate use fungal solid-state (SSF) and submerged culture fermentation (SCF) with agro-industrial residues as substrates to enhance production polyphenols their possible uses food additives. Some (peels, pulps seeds) are an important source phenolic acids (p-coumaric, p-hydroxybenzoic, chlorogenic, cinnamic, feruli...

Background: One of the causes death is diabetes. Anti-diabetic drugs currently available do not work optimally because some have been reported to side effect and resistance. Objective: This study aimed flavonoid compounds from Syzygium cumini var. album with greatest anti-diabetic activity lower toxicity than acarbose. Materials Methods: research an in silico nine album, starting PASS online wa...

The root of Geranium collinum Steph is known in Tajik traditional medicine for its hepatoprotective, antioxidant, and anti-inflammatory therapeutic effects. The present study was conducted to evaluate of potential antidiabetic, antioxidant activities, total polyphenolic and flavonoid content from the different extracts (aqueous, aqueous-ethanolic) and individual compounds isolated of the root p...

Phenolic acids, flavanols, flavonols and stilbenes (PAFFS) were isolated from whole grapes, juice, or pomace and purified using enzymatic hydrolysis. Only anthocyanin mono-glucosides and a few of the oligomers from Cynthiana grape (Vitis aestivalis) were analysed. Flavonoid-anthocyanin mono-glucosides (FA) were isolated using methanol/0.1% hydrochloric acid extraction. In addition, crude extrac...

BACKGROUND/AIM The flavonoid quercetin exerts significant anti-inflammatory activity against chronic infections, including periodontal disease. However, it is unclear whether combination of quercetin with other flavonoids enhances antioxidant and anti-inflammatory activity. To clarify the molecular mechanism responsible for the anti-inflammatory activity of quercetin, we investigated the antiox...

Four hitherto undescribed Clostridium strains capable of cleaving the C ring of quercetin, kaempferol, and naringenin at C-3-C-4 were isolated from the fecal flora of humans. None of the strains cleaved catechin. C-ring fission occurred when the substrate was either in solution or in suspension. Mixed cultures of flavonoid-hydrolyzing bacteria, flavonoid-cleaving bacteria, and Escherichia coli,...

Analytical data are reported for 20 flavonoids (as aglycones) determined for more than 60 fresh fruits, vegetables, and nuts collected from four regions across the United States at two times of the year. Sample collection was designed and implemented by the Nutrient Data Laboratory (USDA). Analyses of eight flavan-3-ols (catechin, catechin gallate, epicatechin, epicatechin gallate, epigallocate...

The biological activity of mushroom consumption is achieved by the antioxidant effect of constituent biomolecules released during digestion. In the following study, the consumption of mushroom fungi was determined to increase the number of Lactobacillus and Bifidobacterium strains within the colon. The main phenolic antioxidant compounds identified were both gentisic and homogentisic acids. Mor...

AIM To determine overall cardiac effects of flavonoid catechin on ischemia-reperfusion injury in isolated rat hearts in vitro and in vivo. METHODS After perfusing hearts at the pressure of 70 mm Hg, coronary perfusion was interrupted for 30 minutes and then re-established. There were four experimental groups, with 10 rats each. The first group received 100 micromol/L of catechin added to the ...
