title: A new triterpene saponin from Chenopodium ficifolium.
abstract: The new triterpene saponin 3-O-beta-D-glucopyranoside, 28-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosiduronic acid oleanolate was isolated from the roots of Chenopodium ficifolium. The known compounds stigmasterol-3-O-glucoside and 3-O-beta-D-glucopyranosiduronic acid, 28-beta-D-glucopyranosyl oleanolate were also isolated. The latter compound, oleanolic acid, beta-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.
