Stercufoetin A, new oleanane-type triterpenoid from the leaves of L.

From the leaves of L., one new oleanane-type triterpenoid, named stercufoetin A () together with four known ones, vergatic acid (), -amyrin (), oleanolic acid () and maslinic acid were purified by diversely chromatographic methods. Their structures were proposed by HR-APCI-MS and NMR experiments. Compounds were notified for the first time from this species. Compound showed weak cytotoxic effect against three human cancer cell lines (MCF-7, HepG2 and HeLa) using SRB assay.
