摘　　要：本文采用微分脉冲伏安法研究了几种黄酮化合物沙苑子甙、水飞蓟宾、葛根素、黄芩甙及芦丁等的电化学性质 ,结果表明 ,这几种化合物均有良好的电化学还原活性 ,但它们的还原行为具有一定的差异 ,各种化合物的主要还原电流的峰高与浓度均呈良好的线性关系 ,从而可采用该方法对这几种化合物进行定量测定 。The electrochemical properties of the flavone compounds such as complanatuside,silimarin,puerarin,baicalin and rutin have been studied with the method of differential pulse voltammetry in this paper. The results showed that the electrochemical reduction activity of those flavone compounds were quite good but there were some difference between them.The height of main reduction peak of every compound linearly responded to the concentration respectively.So it could be used to determination the content of each compound and it is possible to detect the single one of those flavone compounds from their mixture.
