First example of 11,12-epoxytaxane-glucoside from the needles of taxus cuspidata

摘要

A new taxane-glucoside was isolated from the needles of Taxus cuspidata. The structure was established as 2 alpha,9 alpha,10 beta-triacetoxy-11,12-epoxytax-4(20)-en-13-one-5 alpha-O-beta-D-glucopyranoside (1) on the basis of 1D- and 2D spectral analyses.
