Abstract
Three new cycloartane-triterpene glycosides, astraverrucin IV, V and VI, we re isolated from the aerial parts of Astragalus verrucosus. Based on spectr oscopic analysis (IR, 1D and 2D-NMR, FABMS), the structures of the saponins were established to be cycloastragenol 3-O-[alpha-L-rhamnopyranosyl(1-->4) -beta-D-glucopyranoside], cycloastragenol 3-O-[alpha-L-rhamnopyranosyl(1--> 4)]-beta-D-(3-O-acetyl)glucopyranoside and cycloastragenol 3-O-[alpha-L-rh amnopyranosyl (1 --> 4)]-beta-D-(6-O-acetyl)-glucopyranoside. D-pinitol and astraverrucin I were also obtained. (C) 1998 Elsevier Science Ltd. All rig hts reserved.
