摘要：

Three new bicyclic taxane diterpenes were isolated from the needles of the Japanese yew, Taxus cuspidata Sieb. et Zucc. Their structures were established to be 7,9,10,13-tetraacetoxy-5-cinnamoyloxy-4-hydroxy-methyl-8,12,15,15-tetramethyl-bicyclo[9.3.1] pentadeca-3,8,11-trien-2-ol (2,20-dideacetyl taxuspine X), 7,9,10,13,20-pentaacetoxy-5-cinnamoyloxy-8,12,15,1 5-tetramethyl bicyclo[9.3.1] pentadeca 3,8,11-trien-2-ol (2-deacetyl taxuspine X), and 9,10,13,20-tetraacetoxy-5-cinnamoyloxy-8,12,15,15-tetramethyl-bicyclo[9.3.1] pentadeca-3,8,11-trien-2,7-diol (2,7-dideacetyl taxuspine X) with the aid of spectroscopic techniques and by comparing with taxuspine X.
