✦ Synopsis

A new taxane glycoside was isolated from a methanol extract of the needles of Taxus cuspidata. The structure was established as 2a,9a,10b-triacetoxytaxa-4(20),11-dien-13-one- 5a-O-b-D-glucopyranoside (1) on the basis of 1D-and 2D NMR and high-resolution fast atom bombardment mass spectral analyses.
