| 摘 要： | 本文研究了射干、芬尾中三种异黄酮:鸢尾甙、鸢尾甙元和野鸢尾甙元的方波伏安分析方法。在缓冲溶液中,三种异黄酮在方波伏安图上-1.34V(vs.Ag/AgCl)左右具有很好的还原峰形。峰电流与异黄酮浓度呈线性关系。本法较简单、快速、准确、灵敏、重现性好。

| 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. |
