TWO NEW TAXOIDS FROM THE NEEDLES AND STEMS OF TAXUS CHINENSIS

摘要

Two new taxoids,named 10-O-benzoyl-15-O-acetyltaxumairol X (1) and 5-O-acetyl-20-O-deacetyl-4,20-p-hydroxylbenzylidenedioxytaxuyunnanine L (2),were isolated from the needles and stems of Taxus chinensis.Their structures were determined on the basis of combined 1D and 2D spectral techniques.
