There is growing interest in flavonoids for their wide array of biological actions. In neurodegenerative disorders these naturally occurring polyphenolic compounds, are known to inhibit proinflammatory mediators such as in TNF–? and IL-6 in lipopolysaccharide (LPS) stimulated neuronal degeneration, which are associated with Alzheimer’s and Parkinson’s disease. Recent studies on flavonoids have ...

Our previous study revealed that aqueous extract of grape pomace obtained from a winemaking process could exert bactericidal action upon photo-irradiation via reactive oxygen species (ROS) formation. In the present study, we focused on chemical composition and prooxidative profile of the extract. Liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) analysis showed that po...

The study aimed to investigate the biological properties of protein fraction brewers’ spent grain (BSG) and its sediments as well techno-functional BSG (BSGP). was incubated with 0.5% protamex a combination flavourzyme, in addition control (incubation without protease). results showed that enzymatic treatment enhanced antioxidant activity BSGP. Compared sediment fraction, BSGPs had higher capac...

Polyphenolic extracts and fractions of selected peach and plum genotypes were evaluated for cell viability and antiproliferation activity in vitro against an estrogen independent MDA-MB-435 and estrogen dependent MCF-7 breast cancer cell lines and one non-cancerous breast line MCF-10A. All extracts showed a phenolic dose-dependent cytotoxic effect against MDA-MB-435, weak activity against MCF-7...

Leptadenia pyrotechnica Forssk is a traditional medicinal herb used for treatment of inflammatory diseases and cancer. In this research, the aqueous ethanolic crude extract of Leptadenia pyrotechnica aerial parts, along with its ethyl acetate, n-butanol and water partitioning fractions were evaluated for their antioxidant capacity, polyphenolic content, anti-inflammatory and anti-cancer propert...

The preventive effect of Moringa oleifera polyphenolic fraction (MOPF) on cardiac damage was evaluated in isoproterenol (ISO) induced cardiotoxicity model of Wistar rats. Male rats in different groups were treated with MOPF orally at the dose of 50, 100 and 150 mg/kg/day for 28 days and were subsequently administered (s.c.) with ISO (85 mg/kg body weight) for the last two days. At the end of th...
