Resveratrol is a polyphenolic compound, also called astragalus triphenols, which is a chemical preventive agent for tumor, and also a chemical preventive agent for reducing platelet aggregation, preventing and treating atherosclerosis and cardiovascular and cerebrovascular diseases. From peanut , grape (red wine), Polygonum cuspidatum, mulberry and other plants.
Resveratrol exists in the form of free form and glycoside under natural conditions. The chemical structure of resveratrol and its glycosides also exist cis and trans isomers respectively. That is, cis-resveratrol (cis-Res), trans-resveratrol (trans-Res) and cis-resveratrol glycoside (cis-PD), trans-resveratrol glycoside (trans-PD). Resveratrol was released from the latter two forms under the action of glucosidase in the intestine. Resveratrol existed mainly in trans form in plants. The physiological activity of trans-isomer was stronger than that of cis-isomer.
