Two triterpene glycosides of the oleanane series, melilotoside A2 and previously known adzukisaponin V, were isolated from the roots of Melilotus tauricus (L.) Pall. (Fabaceae). The structures of the glycosides were proved based on chemical transformations. Melilotoside A2 had the structure soyasapogenol B 3-O-β-D-glucouronopyranoside; adzukisaponin V, soyasapogenol B 3-O-[α-L-rhamnopyranosyl-(1-2)-β-Dglucopyranosyl-(1-2)-β-D-glucuronopyranoside].
