Abstract

Two new taxoids, 2alpha-acetoxy-2',7-dideacetoxyaustrospicatine (1) and decinnamoyltaxinine E (2), have been isolated from the extracts of the seeds of the Chinese yew Taxus chinensis (Pilg.) Rehd. in addition to taxuspine Z (3), taxin B (4), taxezopidine G (5), 7, 2'-bisdeacetoxyaustropicatine (6), 5alpha-cinnamoyl-9alpha,10beta, 13alpha-triacetoxytaxa-4(20),11-diene (7), taxachitriene A, 20-deacetyltaxachitriene A, 13-O-acetylbrevifoliol, taxinines A and J, and taxacin. The structures of these compounds were elucidated on the basis of spectral analysis and chemical derivatizations.
