title: A new triterpenoid saponin from Ardisia crenata.
abstract: A new triterpenoid saponin, ardicrenin (1), isolated from the roots of Ardisia crenata Sims was established as cyclamiretin A-3-O-[alpha-L-rhamnopyranosyl-(1----4)-beta-D-glucopyranosyl-(1----4)][ beta-D-glucopyranosyl-(1----2)]-alpha-L-arabinopyranoside. A partially hydrolyzed saponin (3) was characterized as cyclamiretin A-3-O-beta-D-glucopyranosyl-(1----2)-alpha-L-arabinopyranoside .
