Abstract
Two minor triterpenoid saponins, ardisicrenoside G [3β-O-{α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-16α, 28-dihydroxyolean-12-en-30-oic acid] and ardisicrenoside H [3β-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-16α, 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.
