An investigation of Taxus brevifolia extracts afforded two taxoids characterized by the A-nortaxol ring system. These were identified as 7,13-dideacetyl-9,10- debenzoyltaxchinin C [1] and 9-deacetyl-9-benzoyl-10-debenzoylbrevifoliol [4]. Structures were elucidated by spectroscopic methods, and in particular by comparison of nmr data with those of taxchinin C and brevifoliol.
