- 中文摘要: Five Taxane derivatives were isolated from Taxus mairei. Their structures were determined by spectroscopic methods and their physical constants were identical with the literature values. These are Taxa-4(20),11-diene-2.alpha., 5.alpha.,7 .beta.- tetrol-5.alpha.,7.beta., 10.beta.-triacetate-2.alpha.-.alpha.-methylbutyrate(I);Taxa-4(20),11-diene- 2.alpha.,5.alpha.,9.alpha.,10.beta., 13.beta.-pentol-2.alpha., 9.alpha.,10.beta., 13.alpha.-tetraacetate-5.alpha.-cinnamate( II); Taxa-4(20), 11- diene-5.alpha.,7.beta.,9.alpha.,10.beta., 13.alpha.-pentol-pentaacetate(III);7.beta.-acetate-O-taxinine A(IV), 1.beta.-hydroxy-baccatin-I(V).
