Abstract

Three new taxoids were isolated from the seeds of the Chinese yew, Taxus chinensis var mairei, their structures were established as 9α,13α-diacetoxy-5α-cinnamoyloxy-11(15 → 1)-abeo-taxa-4(20), 11-diene-10β,15-diol, 2α,9α,10β-triacetoxy-taxa-4(20),11-diene-5α,13α-diol and 2α,7β,10β-triacetoxy-5α-cinnamyloxy-9α-hydroxy-taxa-4(20),11-diene-13-one on the basis of 1D, 2D NMR, and MS spectral analyses.
