title: Triterpene glycosides from the bark of Robinia pseudo-acacia L. II.
abstract: From the bark of Robinia pseudo-acacia L., six new triterpene glycosides, Robiniosides E--J, were isolated and their structures were elucidated as abrisapogenol B 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D-galactopyranosyl(1-->2)-beta-D - glucuronopyranoside (1), abrisapogenol B 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D- glucopyranosyl(1-->2)-beta-D-glucuronopyranoside (2), 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D-galactopyranosyl(1-->2)-beta-D - glucuronopyranosyl abrisapogenol B 22-O-alpha-L-rhamnopyranoside (3), 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D- glucopyranosyl(1-->2)-beta-D-glucuronopyranosyl abrisapogenol B 22-O-alpha-L-rhamnopyranoside (4), 3-O-alpha-L- rhamnopyranosyl(1-->2)-beta-D-galactopyranosyl(1-->2)-beta-D-glucuron opyranosyl abrisapogenol E 30-O-beta-D-apiofuranosyl(1-->6)-beta-D-glucopyranoside (5) and 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D-glucopyranosyl(1-->2)-beta-D- glucuronopyranosyl abrisapogenol E 30-O-beta-D-apiofuranosyl(1-->6)-beta-D-glucopyranoside (6), respectively.
