Study on Chemical Constituents of Root-bark of Ficus tsiangii

Hanhong Xu

Abstract

The chemical constituents of the root bark of Ficus tsiangii were investigated.Merr.ex Corner compounds were separated and purified by column chromatography.According to NMR and MS their structures were elucidated to be: β-amyrin acetate(1),taraxerone(2),taraxerol(3),2α-hydroxyoleanolic acid(4),oleanolic acid(5),β-stosterol(6),stigmasterol(7),chrysoeriol(8),4′,5,7-trihydroxyisoflavone(9).Literature survey in CA showed that compounds 1-9 were isolated from this plant and compound 2 was isolated from the Ficus genus for the first time.
