Summary
From the leaves ofEleutherococcus senticosus four glycosides of oleanolic acid have been isolated, and they have been called eleutherosides I, K, L, and M. Eleutherosides I and K are biosides whose carbohydrate chains consist of L-arabinose and L-rhamnose residues. Eleutherosides L and M are pentaosides and differ from I and K, respectively, by the fact that they contain a trisaccharide consisting of D-glucose and L-rhamnose attached by an O-acylglycosidic bond to the carboxy group. The absence of branching and of 1,3 bonds in the carbohydrate chains of the eleutherosides has been shown.
