Sesquiterpene polyol esters from Tripterygium wilfordii.
The extract (T(II)) of Tripterygium wilfordii Hook f. afforded four sesquiterpene esters: 1beta,2beta,5alpha,8beta,11-pentaacetoxy-4alpha-hydroxy-3alpha(2'-methylbutanoyl)-15-nicotinoyl-7-oxo-dihydroagarofuran; 1beta,5alpha,11-triacetoxy-7beta-benzoyl-4alpha-hydroxy-8beta-nicotinoyl-dihydroagarofuran; 1beta,2beta,5alpha,11-tetraacetoxy-8alpha-benzoyl-4alpha-hydroxy-7beta-nicotinoyl-dihydroagarofuran; 5alpha-benzoyl-4alpha-hydroxy-1beta,8alpha-dinicotinoyl-dihydro- agarofuran as well as one other known sesquiterpene ester. Their structures were established on the basis of spectroscopic studies.
