M. Udayama et al., A NEW OLEANENE GLUCURONIDE HAVING A BRANCHED-CHAIN SUGAR FROM MELILOTUS-OFFICINALIS, Chemical and Pharmaceutical Bulletin, 46(3), 1998, pp. 526-527
A new oleanene glucuronide called melilotus-saponin O-1 (1) was isolat
ed together with three known ones from the roots of Melilotus officina
lis (L.) PALLAS (Leguminosae). The structure of 1 was determined to be
galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl soyasapogenol B by
spectroscopic and chemical methods.
