Flavonoid compounds in vegetable-based diets bring a significant contribution to the role of fruits and vegetables as health-promoting foods. This review summarizes the available data concerning physiological and therapeutical effect of plan flavonoid quercetin. Quercetin has a number of beneficial influence on health because of their antioxidant, anti-inflammatory, anti-proliferative, anti-carcinogenic and anti-diabetes properties. Effects of quercetin have been explained by its interference with cellular enzymes, receptors, transporters and signal transduction systems. Despite the available data reviewed here, the targets, effects, absorption, metabolism and areas of practical application of quercetin are still poorly understood, therefore further studies in this areas are required.
