Abstract: Five compounds were isolated from the bark of Taxus yunnanensis Cheng et L. K. Fu. Based on spectral IR, MS, 1H-NMR, 13C-NMR and physico-chemical constant analysis, they were identified as 7-epi-taxol B ( Ⅰ ), 1, 13-diacetoxy-10-deacetyl baccatin Ⅲ (Ⅱ ), taxol C-7-xylose (Ⅲ), taxol (Ⅳ), 3-epi-ursolic acid (Ⅴ). Compounds Ⅰ and Ⅱ were newly identified.
