The structures of 6 new oleanene glycosides (1-6) isolated from the leaves of Acanthopanax japonicus FRANCH et. SAVART (Araliaceae) were elucidated by mass, 1D, and 2D NMR spectroscopy. The structures of 1-6 were established as 28-O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl] ester of 3β, 23-dihydroxy-olean-12-en-28, 29-dioic acid, 3β, 30-dihydroxy-olean-12-en-23, 28-dioic acid, 3β, 29-dihydroxy-olean-12-en-23, 28-dioic acid (=dianic aicd), 3β-dihydroxy-olean-12-en-23, 28-dioic acid (=gypsogenic acid), 3β, 29-dihydroxy-23-oxo-olean-12-en-28-oic acid, and 3β-hydroxy-23-oxo-olean-12-en-28, 29-dioic acid, designated acanjaposide D (1), E (2), F (3), G (4), H (5), and I (6), respectively.
