Article abstract of DOI:10.1016/S0031-9422(00)98554-6

Four novel 3,28-O-bisglycosidic triterpenoid saponins were isolated from the mature fruits of F. japonica.They were characterized as the 28-O-α-L-rhamnopyranosyl-(1->4)-β-D-glucopyranosyl-(1->4)-β-D-glucopyranosides of 3-O-α-L-arabinopyranosyl echinocystic acid, 3-O-α-L-arabinopyranosyl hederagenin, 3-O-β-D-glucopyranosyl-(1->2)-α-L-arabinopyranosyl oleanolic acid and 3-O-β-D-glucopyranosyl-(1->2)-α-L-arabinopyranosyl hederagenin respectively. - Keywords: Fatsia japonica; Araliaceae; mature fruits; 3,28-O-bisglycidic triterpenoid saponins.
