title: New taxanes from the seeds of Taxus mairei.
abstract: Two new taxoid metabolites were isolated from the methanol extract of the Taxus mairei seeds. Their structures were established as 2alpha-hydroxy-9alpha,10beta,13alpha-triacetoxy-5alpha-cinnamoyloxytaxa-11-en-4beta,20-epoxide (1) and 2'-acetyl taxol (2) on the basis of spectral analysis.
