A new metabolite with a new substitution pattern from the seeds of the Chinese Yew, Taxus mairei

Chem Biodivers. 2007 Jan;4(1):84-8. doi: 10.1002/cbdv.200790009.

Abstract

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 5alpha,15-dihydroxy-7beta,9alpha-diacetoxy-11(15-->1)abeo-taxa-4(20),11-dien-13-one (1) on the basis of spectral analysis including (1)H- and (13)C-NMR, HMQC, HMBC, NOESY, and confirmed by HR-FAB mass spectrometry.
