从白喉乌头(Aconitum leucostomum Vorosch.)中分离得到13个二萜生物碱,采用HR-ESI- MS,1D NMR和2DNMR等波谱技术确定了它们的结构.其中一个为新的C18二萜生物碱:刺乌宁,其余为已知化合物.同时考察了其中12个化合物对甜菜夜蛾3龄幼虫的拒食活性,结果表明化合物氨茴酰基牛扁碱和东乌头定的活性较好(EC50<1mg/cm2),其次是N-acetylsepaconitine,赣乌碱和N-去乙酰高乌甲素(EC50<2 mg/cm2).

A new C18 diterpenoid alkaloid,leucostonine(1),was isolated from the whole plant of Aconitum leucostomum Vorosch.,together with twelve known diterpenoid alkaloids.Their structures were elucidated on the basis of extensive spectroscopic analysis,including HR-ESI-MS,1D NMR and 2D NMR spectra.12 compounds were tested for their antifeedant activity against larvae of Spodoptera exigua Hiibner.Anthranoyllycoctonine and avadharidine showed considerable potent antifeedant activity(EC50<1 mg/cm2),followed by N-acetylsepaconitine,finaconitine and N-deacetylappaconitine(EC50<2 mg/cm2).
