Abstract
Three isoflavones: irigenin, tectorigenin and tectoridin in Belamcanda chinensis (L.)DC. and Iris tectorum Maxim were determined by square wave voltammetry. At the potential of -1.34 V (vs Ag/AgCl) the isoflavones gave well-defined peaks in the buffer solutions of pH3-5. An excellent linear relationship was obtained between the peak current and concentration. The method can be used to analyze small amounts of sample.
摘要
采用方波伏安法测定了射干和鸢尾中的三种异黄酮
鸢尾黄素、鸢尾甙元及鸢尾甙。在-1.34 V（vs Ag/AgCl）电位下，异黄酮在pH3 - 5的缓冲溶液中产生清晰的峰。峰电流与浓度之间呈现出良好的线性关系。该方法可用于分析少量样品。
