The results showed as follows: 1 Extraction of gelsemium total alkaloids. Total alkaloids were extracted with 95 per cent ethanol. The extract rate was 0.519 per cent and the extract purity were 88.02 per cent and 87.38 per cent; Total alkaloids were extracted with chloroform .The extract rate was 0.416 per cent and the extract purity were 89.02 per cent and 94.52 per cent. 2 Isolation of gelsemium total alkaloids with TLC. Total alkaloids contained five or more alkaloids. The optimal developing agent was chloroform :methanol :ethyl acetate(9:l:0.3),the optimal eluent was methylene chloride:methanol(92:8). 3 Isolation of total alkaloids with column chromatography. Alkaloid A and alkaloid B were obtained, alkaloid B was identified as koumine.

研究结果如下：1、钩吻总碱的提取：用95％的乙醇提取钩吻生物碱提取率为0.519％，其提取物纯度为88.02％、87.35％；用氯仿提取钩吻生物碱提取率为0.416％，其提取物纯度为89.02％、94.52％。2、钩吻总碱的薄层层析分离：总碱中含有5种或5种已上的生物碱；氯仿：甲醇：乙酸乙酯(9：1：0.3)是最佳薄层层析的展开剂；二氯甲烷：甲醇(92：8)是柱层析的最佳洗脱剂。3、钩吻总碱的柱层析分离：共得到两种钩吻生物碱单体成分碱A和碱B，碱B为钩吻素子，碱A可能是钩吻素甲。4、钩吻总碱的急性毒性试验：钩吻总碱小鼠腹腔注射的半数致死量LD_(50是：7.38mg／kg，95％的可信限范围为：6.67mg／kg～7.94mg／kg。
