Abstract:Resveratrol (RSV), as one of the most abundant nonflavonoid polyphenolic compounds, is widely found in natural plants. Its biological properties include antioxidant, antiinflammatory, antibacterial, antiviral, and regulating cell metabolism. RSV has been widely used in human health care and animal production. To provide a reference for further research and development application, the source, physicochemical characters, bioavailability, biological properties of RSV and its mechanism of action were brief summarized in this paper.
