From the bark of Robinia pseudo-acadia L., six new triterpene glycosides, Rpbiniosides E-J, were isolated and their structures were elucidated as abrisapogenol B 3-O-α-L-rhamnopyranosyl(1→2)-β-D-galactopyranosy(1→2)-β-D-glucuronopyranoside (1), abrisapogenol B 3-O-α-L-rhamnopyranosy(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucuronopyranoside (2), 3-O-α-L-rhamnopyranosyl(1→2)-β-D-galactopyranosyl(1→2)-β-D-glucuronopyranosyl abrisapogenol B 22-O-α-L-rhamnopyranoside (3), 3-O-α-L-rhamnopyranosyl(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucuronopyranosyl abrisapogenol B-22-O-α-L-rhamnopyranoside (4), 3-O-α-L-rhamnopyranosyl(1→2)-β-D-galactopyranosyl(1→2)-β-D-glucuronopyranosyl abrisapogenol E 30-O-β-D-apiofuranosyl(1→6)-β-D-glucopyranoside (5) and 3-O-α-L-rhamnopyranosyl(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucuronopyanosyl abrisapogenol E 30-O-β-D-apiofuranosyl(1→6)-β-D-glucopyranoside (6), respectively.
