毛裂蜂斗菜化学成分的研究

STUDIES ON THE CHEMICAL CONSTITUENTS OF PETASITES TRICHOLOBUS FRANCH.

从毛裂蜂斗菜 ( Petasites tricholobus Franch.)的石油醚提取物中首次分离得到6个化合物 ,运用 IR,EI- MS,HRMS,1H NMR,13C NMR,DEPT等光谱方法确定了它们的结构。它们分别是 :A1,β-谷甾醇 ;A2 ,三十二碳酸 ;A3,羽扇豆醇 ;A4 ,Bakkenolide-B;A5,Bakkenolide- D和 A6,Bakkenolide- E。

Six compounds were isolated from Petasites tricholobus Franch.Their structures were determined on the basis of physical evidences.They were:A 1,β sitosterol;A 2,Dotri acontanoic acid;A 3,lupeol;A 4,Bakkenolide B;A 5,Bakkenolide D and A 6,Bakkenolide E.
