Chemical examination of the seeds of the Chinese yew, Taxus yunnanensis Cheng et L. K. Fu and japanese yew, T. cuspidata Sieb et Zucc resulted in the isolation of three new and rare rearranged abeotaxane type of diterpenoids in addition to several known compounds. The structures of the new taxoids have been established as 9#alpha#, 13#alpha#-diacetoxy-11(15 -> 1)abeotaxa-4(20), 11-diene-5#alpha#, 10#beta#, 15-triol (1), 9#alpha#, 13#alpha#-diacetoxy-10#beta#-benzoyloxy-5#alpha#-(3'-dimethylamino-3'-phenyl)-propionyloxy-11(15 -> 1)abeotaxa-4(20), 11-diene-15-ol (2), and 2#alpha#, 7#beta#, 13#alpha#-triacetoxy-10#beta#-hydroxy-5#alpha#-(3'-dimethylamino-3'-phenyl)-propionyloxy-2(3 -> 2O)-abeo-taxa-9-one (3) by a study of their spectral data.
