Abstract

The previously known triterpenoid 3-O-α-L-arabinopyranosides of oleanolic and echinocystic acids and hederagenin, 3-O-β-D-glucopyranosyl-(1→2)-O-α-L-arabinopyranosides of oleanolic acid and hederagenin, in addition to 28-O-α-L-rhamnopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl ethers of the 3-O-α-L-arabinopyranoside of hederagenin, and 3-O-β-D-glucopyranosyl-(1→2)-O-α-L-arabinopyranosides of oleanolic acid and hederagenin, respectively, are isolated from leaves ofFatsia japonica(Araliaceae). The structures of the glycosides are confirmed by chemical methods and13C NMR spectroscopy
