A Novel Sesquiterpene Polyol Ester from Celastrus Angulatus and its Antitumor Activities

摘要

A new sesquiterpene polyol ester was isolated from the leaves of Celastrus angulatus. itsstructure was determined as 1 6. 2 6. 9 a-triacetoxy-8 a-(a-hydroxyl-isobutyryloxy)-15-benzoyloxy-4 a-hydroxy-dihydroagarofuran by means of NMR. MS and IR spectral analysis.Preliminary biological study on antitumor activity revealed that this compound showed strongnonselective cytotoxicity against four of the NCI panel cell lines.
