摘要:

Three new bicyclic taxane diterpenes were isolated from the needles of the Japanese yew,Taxus cuspidataSieb. et Zucc. Their structures were established to be 7,9,10,13-tetraacetoxy-5-cinna-moyloxy-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-8,12,15,15-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-dide-acetyl taxuspine X) with the aid of spectroscopic techniques and by comparing with taxuspine X.
