Review on Activities of Quercetin

Quercetin is a flavonoid with a range of biological activities that contribute to its potential health benefits. Due typically to its potent antioxidant activity, quercetin is one of the bioactive materials that is frequently used in Traditional Chinese medicine and herbal medicine. In the last years, there were many investigations into the antioxidant activities of quercetin, like its influence on GSH, enzymatic activity, signal transduction pathways, and ROS induced by environmental and toxicological factors. The antioxidant activity of quercetin, particularly its metal ion complexes and complex ions, has dominated chemical studies on the compound. Here, we report the recent advances in antioxidant activities, antimicrobial activities, antitumour activities, anti -inflammatory activities of quercetin.
