中文摘要：
对丽江紫乌头中的二萜生物碱进行研究.利用反复硅胶柱层析,重结晶等分离手段从中分离鉴定了6个二萜生物碱：查斯曼宁（chasmanineⅠ）,塔拉萨敏（talatizamineⅡ）,草乌甲素（crassicauline AⅢ）,丽江乌头碱（foresaconitineⅣ）,acoforestinine（Ⅴ）,滇乌碱（yunaconitineⅥ）.其中化合物Ⅰ、Ⅲ、Ⅳ、Ⅴ为首次从该种植物中分离得到.
英文摘要：
The diterpenoid alkaloids of Aconitum episcopale Levl. were studied and six diterpenoid alkaloids were isolated by silica column chromatography.The structures of theses compounds were elucidated as chasmanineⅠ,talatizamine Ⅱ,crassicauline A Ⅲ,foresaconitine Ⅳ,acoforestinine Ⅴ,yunaconitine Ⅵ by spectral methods.Compounds Ⅰ,Ⅲ,Ⅳ,Ⅴ were isolated from this plant for the first time.
