Two new triterpenoidal glycosides from Medicago polymorpha L.
Two new triterpenoid glycosides called medicago-saponins P1 (1) and P2 (2) were isolated together with five known glycosides from the aerial parts of Medicago polymorpha L. (Leguminosae). The structures of 1 and 2 were determined to be 3-O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranosyl caulophyllogenin 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside and the desglucoside of 1.
