Abstract

A new 2(3 → 20)abeotaxane with an unusual 13β-substitution pattern and a new 6/8/6-ring taxane were isolated from the methanol extract of the needles of Taxus cuspidata. The structures were established as 2α,7β-diacetoxy-5α,10β,13β-trihydroxy-2(3 → 20)abeotaxa-4(20), 11-dien-9-one (1) and 2α,5α,7β,9α, 13α-pentahydroxy-10β-acetoxytaxa-4(20),11-diene (2) on the basis of 1D and 2D NMR spectral data and high-resolution FAB-MS analyses.
