摘要：
A new taxoid metabolite with a new substitution pattern was isolated from the methanol extract of the seeds of Taxus mairei, and its structure was established as 5 alpha,15-dihydroxy-7 beta 9 alpha-diacetoxy-11(15 -> 1)abeo-taxa-4(20),11-dien-13-one (1) on the basis of spectral analysis including H-1- and C-13-NMR, HMQC, HMBC, NOESY, and confirmed by HR-FAB mass spectrometry.
