摘要： 秋水仙碱是近年来新发现的有前途的抗癌植物有效成分。秋水仙碱的测定方法,如容量滴定法[1]、电位滴定法[2]、紫外分光光度法[3]、荧光分析法[4]和高效液相色谱法[5]等,手续均不太简便。电化学分析研究秋水仙碱主要有阳极伏安法[6]和交流极谱法[7],前者因使用固态电极,重现性较差。后者用非水溶剂作介质,灵敏度不高。

Abstract: The differential pulse polarographic behaviour of colchicine have been investigated. A well defined peak was observed in a 0.6% (C4H9)4NCl-B. R. buffer solution (pH 1.81) at potential Of -0.90 V(vs Ag/AgCl). An excellent linear relationship existed between the concentration(9.6×10-7～8.6×10-5mol/L) and peak current. This method provides a rapid and simple way to determine colchicine in pharmaceutical preparations and I phigenia indica Kunth et Benth.

Key words: colchicine, differential pulse polarography, determination
