从长苞铁杉茎的甲醇提取物中分离出两种新的重排羊毛甾烷三萜类化合物，命名为 tsugalide A (1) 和 tsugalide B (2)。新化合物的化学结构是在广泛的一维和二维核磁共振波谱的基础上建立的，并且化合物1的构型通过X射线晶体学进一步证实。
Two new rearranged lanostane triterpenoids, named tsugalide A (1) and tsugalide B (2), were isolated from the MeOH extract of the stem of Tsuga longibracteata Cheng. Their chemical structures of the new compounds were established on the basis of extensive 1D and 2D NMR spectroscopy, and the configuration of compound 1 was further confirmed by X-ray crystallography.
