A new taxane with an opened oxetane ring from the needles of Taxus cuspidata.
A new taxoid metabolite was isolated from the MeOH extract of Taxus cuspidata needles. The structure was established as (2alpha,5alpha,7beta,9alpha,10beta,13alpha)-10,13,20-tris(acetyloxy)-1,4,5,7,9-pentahydroxytax-11-en-2-yl benzoate on the basis of spectral analyses including 1H- and 13C-NMR, HMQC, HMBC, and NOESY, and confirmed by HR-FAB-MS.
