Abstract:
Five new triterpenoid saponins, platycoside H [3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl-2beta,3beta,16alpha,23-tetrahydroxyolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside], platycoside I [3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl-2beta,3beta,16alpha,23-tetrahydroxyolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside], platycoside J [3-O-beta-D-glucopyranosyl-2beta,3beta,16alpha,23-tetrahydroxyolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside], platycoside K [3-O-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranosyl-2beta,3beta,16alpha,23,24-pentahydroxyolean-12-en-28-oic acid], and platycoside L [3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl-2beta,3beta,16alpha,23,24-pentahydroxyolean-12-en-28 oic acid], and three known triterpenoid saponins, platycoside F, platycoside B, and platycoside C, were isolated from the roots of Platycodon grandiflorum A. DC. Their chemical structures were elucidated on the basis of their spectral data and chemical evidence.
