摘要

The new triterpenoid saponin 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta-D-glucuronopyranosyl]-3beta, 22alpha-dihydroxyolean-13-en-11-one has been isolated from Ononis spinosa. The new flavonoid glycoside 3-O-[2-O-(E)-beta-coumaroyl-beta-D-galactopyranosyl]-7-O-beta-D-glucopyranosylkaempferol and the new pterocarpan glucoside 3,4-di-O-beta-D-glucopyranosyl-4-hydroxymedicarpin have been obtained from Ononis vaginalis. The structures were determined primarily by NMR spectroscopy. The assignment of NMR signals was performed by means of H-1-H-1 COSY, ROESY, TOCSY, HMQC HMQC-COSY and HMBC experiments.
