ABSTRACT
From the chloroform-soluble fraction of the ethanol extracts of the whole plant of Taxus chinensis var. mairei (Lemee et Lev1), four compounds were isolated by using repeated column chromatography on silica gel and Sephadex LH-20. Based on spectroscopic data (UV, IR, ESI-MS, 1H NMR and 13C NMR), the compounds were identified as taxamairin K (1), 2alpha, 4alpha-dideacetoxy-7beta-benzoyloxy-5beta,20-epoxy-9alpha, 10beta, 13alpha, 15-tetrahydroxy-11(15-->1) abeotaxa-11-ene (2), 7beta-xylosyl-taxol (3), 10-deacetoxy-7-xylosyl-taxol (4). Among them, taxamairin K is a new compound.
