从怒江产云南红豆杉 Taxus yunnanensis中分得 5个非紫杉烷类化合物:3β- hydroxy- 5 α,8α- epidioxyergosta-6,2 2 diene(),β-谷甾醇(β-sitosterol,),pluviatilol(Ⅱ),α-conidendrin()和 secoisolariciresinol(Ⅱ)。其中 是首次从红豆杉科植物中得到。我们利用核磁共振波谱与质谱等技术确定了它们的结构。

Studies on the root of Taxus yunnanensis Cheng et L.K.Fu,grown in Nujiang area,Yunnan Province,resulted in the isolation of 5 non-taxanes:3β-hydroxy-5α,8α-epidioxyergosta-6,22-diene,β-sitosterol,pluviatilol,α-conidendrin and secoisolariciresinol.One of them (3β-hydroxy-5α,8α-epi-dioxyergosta-6,22-diene) was obtained from Taxus L.for the first time.Their structures wereconfirmed by modern spectral analysis (NMR,MS,etc.)
