Abstract

A new oleanene glucuronide called melilotus-saponin O₂ (1) was isolated together with three known ones (soyasaponin i, astragaloside VIII, wistariasaponin D) form the aerial parts of Melilotus officinalis (L>) PALLAS (Leguminosae). The structure of 1 was determined to be 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl-(1→2)-β-D-glucuronopyranosyl melilotigenin by spectroscopic and chemical methods.
