摘要：

Five new diterpenoids, taxchinins A [3], B[4], and C [5], 19-hydroxy-7-epibaccatin III [6], and 10-deacetyl-10-oxobaccatin V [7], have been isolated from the needles and stems of Taxus chinensis together with twelve known compounds including taxol [1]. These structures were elucidated and identified by spectroscopic techniques. A single X-ray crystallographic analysis of taxchinin A [3] determined its unique 5/7/6-membered ring system. Taxchinins B [4] and C [5] were shown to have the same ring system.
