Abstract

Stilbenes have been shown to have cancer chemopreventive activity and to protect lipoproteins from oxidative damage. A method is described for their direct determination in different types of wine using high-performance liquid chromatography with ultraviolet detection. In a survey of 120 commercial wines from Portugal and France, the highest concentrations of stilbenes were found in red wines. The glucosides of resveratrol were present in higher concentrations than the free isomers. Isolation from wine and characterization of trans-astringin in a large quantity are described for the first time.

摘要

已证明芪类化合物具有癌症化学预防活性,并能保护脂蛋白免受氧化损伤。本文描述了一种使用高效液相色谱-紫外检测法直接测定不同类型葡萄酒中芪类化合物的方法。在对来自葡萄牙和法国的120种商业葡萄酒的调查中,发现红葡萄酒中芪类化合物的浓度最高。白藜芦醇的糖苷比游离异构体的浓度更高。首次描述了从葡萄酒中分离并大量表征反式阿魏酸糖苷的过程。
