A new oleanene glucuronide having a branched-chain sugar from Melilotus officinalis.
A new oleanene glucuronide called melilotus-saponin O1 (1) was isolated together with three known ones from the roots of Melilotus officinalis (L.) PALLAS (Leguminosae). The structure of 1 was determined to be 3-O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranosyl-(1--> 3)]- beta-D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl soyasapogenol B by spectroscopic and chemical methods.
