Abstract: A new C - 14 oxygenated taxoid, 14β-hydroxy-baccatin VI (1), together with seven known taxoids, baccatin VI (2), baccatin IV (3), lβ-dehydroxybaccatin IV (4) , taxayunnasin A (5), 2α-deacetyl-2α-benzoyl-13α-acetyltaxayuntin (6), 5α-hydroxy-2a, 7β, 9α, 10β, 13α-pentaacetoxy-4 (20), 11-taxadiene (7) and taxacin (8) were isolated from the ethanolic extract of leaves and stems of Taxus chinensis (Pilg) Rehd. The structures of the compounds were elucidated by spectroscopic tech-niques. The detailed 13C and 1H 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.

Key words: Taxus chinensis
