Potentially cytotoxic triterpenoids from the root bark of Siphonodon celastrineus Griff.
A new oleanane-triterpene, 3beta-acetoxy-11alpha-benzoyloxy-13beta-hydroxyolean-12-one (1), was isolated along with a known quinone-methide triterpene, pristimerin (2), from the root bark of Siphonodon celastrineus Griff., a Thai medicinal plant of the family Celastraceae. Their structures were determined based on spectroscopic analysis.
