Minor triterpenoid saponins from Ardisia crenata.
Two minor triterpenoid saponins, ardisicrenoside G [3 beta-O-{alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->4)- [beta-D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl}-16 alpha,28-dihydroxyolean-12-en-30-oic acid] and ardisicrenoside H [3 beta-O-{beta-D-xylopyranosyl-(1-->2)-beta-D- glucopyranosyl-(1-->4)-[beta-D-glucopyranosyl-(1-->2)]-alpha-L- arabinopyranosyl}-16 alpha,28-dihydroxyolean-12-en-30-oic acid] were isolated from the roots of Ardisia crenata. Structural assignments are based on NMR, MS and chemical reactions.
