A new triterpene saponin from Chenopodium ficifolium

Abstract

The new triterpene saponin 3-O-β-D-glucopyranoside, 28-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosiduronic acid oleanolate was isolated from the roots of Chenopodium ficifolium. The known compounds stigmasterol-3-O-glucoside and 3-O-β-D-glucopyranosiduronic acid, 28-β-D-glucopyranosyl oleanolate were also isolated. The latter compound, oleanolic acid, β-sitosterol and its glucoside were isolated from the aerial parts. The identity of these compounds was verified through different chemical and physico-chemical evidences including different 1D and 2D NMR experiments.
