Two new triterpenoid saponins from Platycodon grandiflorum.
Two new triterpenoid saponins, platycoside D [3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl-(1-->6)-beta-D- glucopyranosyl-2 beta, 3 beta, 16 alpha, 23-tetrahydroxyolean-12-ene-28-oic acid 28-O-beta-D- apiofuranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnop yranosyl- (1-->2)-alpha-L-arabinopyranoside] and platycoside E [3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl- (1-->6)-beta-D-glucopyranosyl-2 beta,3 beta,16 alpha,23,24-pentahydroxyolean-12-ene-28-oic acid 28-O-beta-D-apiofuranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-alp ha-L- rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside] were isolated from the roots of Platycodon grandiflorum. Structural determination is based on spectral and chemical evidence.
