A new triterpenoid saponin.3 β-O-{ β-D-glucopyranosyl-(1—4)-[ β-D-glucopyranosyl-[1-2)]- α-L-arabinopyranosyl}-16α, 28-dihydroxyolean-12-en-30-oic acid 30-O- β-D-glucopyranosyl ester(ardisicrenoside N.1),together with two known saponins, ardisicrenoside C(2) and D(3),were isolated from the roots of Ardisia crenata Sim.Their structures were elucidated by extensive spectral analysis and chemical evidences.Saponins 1 showed cytotoxicity against MCI-7 and NCI-H460 cancer cell lines at 11.0μmol/L and 22.1μmol/L in vitro.
