Evaluation of antioxidant potential of flavonoids: an in vitro study.

Abstract

L-rhamnose, galactose, arabinose (eg., quercetin-3glucoside, quercetin-3-rhamnoside, quercetin-3galactoside, quercetin-3-rutinoside (rutin)) (4). Flavonoids exhibit different biological activities influencing on numerous metabolic pathways. Due to their radical scavenging, antioxidant, anti-inflammatory, anti-allergic, anticancer, antiatherosclerotic, antiaggregational and detoxification activities they might be useful for prevention and treatment of many human diseases. Because of the wide spectrum of biological activities and the prevelance of flavonoids in daily life we decided to determine in present study an antioxidant activity of these compounds in in vitro model. Antioxidant activities of numerous flavonoids in plant extracts or natural formulations had intensively been studied (6n8), but little is known about properties of pure flavonoids. In this
