Triterpenoid saponins from Aster auriculatus

Triterpenoid saponins from Aster auriculatus

Planta Medica 64(1): 50-53

Three new triterpenoid saponins, auriculatusaponins A, B, and C, along with one known saponin, 3- O-beta-glucuronylolean-12-en-28-oic acid 28-( O-alpha-rhamnopyranosyl-(1-->2)-alpha-arabinopyranosyl) ester were isolated from roots of Aster auriculatus. On the basis of spectral and chemical evidence, auriculatusaponins A, B, and C were determined as 3beta- O-beta-glucuronyl-16-oxo-12-ene-28-noroleanane, 3beta- O-beta-glucuronyl-16alpha- trans-feruloyloxy-12-en-oleanane, and 3- O-beta-glucopyranosyl-16alpha-hydroxy-olean-12-ene-28-oic acid 28- O-carboxymethyl ester, respectively.
