| Abstract: | A new C - 14 oxygenated taxoid, 14β-hydroxy-baccatin Ⅵ (1), together with seven knowntaxoids, baccatin Ⅵ (2), baccatin Ⅳ (3), 1β-dehydroxybaccatin Ⅳ (4), taxayunnasin A (5), 2α-deacetyl-2α-benzoyl-13α-acetyltaxayuntin (6), 5α-hydroxy-2α, 7β, 9α, 10β, 13α-pentaacetoxy-4(20), 11-taxadiene (7) and taxacin (8) were isolated from the ethanolic extract of leaves and stems ofTaxus chinensis (Pilg) Rehd. The structures of the compounds were elucidated by spectroscopic tech-niques. The detailed 13 C and 1 H NMR data of the seven known compounds were measured in acetone- d6,and the NMR data of taxacin (8) were reported for the first time. |
