On the Saponins from the Leaves of Fatsia japonica DECNE. et PLANCH

Abstract

Two triterpenoid saponins, hederagenin 3-O-β-D-glucopyranosyl (1→2)-α-L-arabinopyranoside (I) and oleanolic acid 3-O-β-D-glucopyranosyl (1→2)-α-L-arabinopyranoside (III), were obtained from the leaves of Fatsia japonica DECNE. et PLANCH. In addition, the structures of two formerly reported Fatsia saponins, "α-fatsin"and"oleanolic acid 3-O-β-D-glucopyranosyl (1→4)-α-L-arabinopyranoside, were revised as being I and III, respectively.
