白藜芦醇是多酚类化合物，主要来源于葡萄（红葡萄酒）、虎杖、花生、桑椹等植物。白藜芦醇是一种生物性很强的天然多酚类物质，又称为芪三酚，是肿瘤的化学预防剂，也是降低血小板聚集，预防和治疗动脉粥样硬化、心脑血管疾病的化学预防剂。 白藜芦醇在自然条件下以自由态和糖苷两种形式存在，白藜芦醇及其糖苷的化学结构还分别存在顺式和反式两种异构体，即顺式白藜芦醇（cis-Res）、反式白藜芦醇(trans－Res）以及顺式白藜芦醇糖苷(cis-PD) 、反式白藜芦醇糖苷（trans-PD）。后两种形式在肠道中糖苷酶作用下释放出白藜芦醇，植物中白藜芦醇主要以反式形式存在。研究表明反式异构体的生理活性强于顺式异构体。
