Abstract

Three new triterpenoid saponins, auriculatusaponins A, B, and C, along with one known saponin, 3-O-β-glucuronylolean-12-en-28-oic acid 28-(O-α-rhamnopyranosyl-(1→2)-α-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 3β-O-β-glucuronyl-16-oxo-12-ene-28-noroleanane (1), 3β-O-β-glucuronyl-16α-trans-feruloyloxy-12-en-oleanane (3), and 3-O-β-glucopyranosyl-16α-hydroxy-olean-12-ene-28-oic acid 28-O-carboxymethyl ester (4), respectively.
