Abstract
Two new triterpenoid saponins, ardisicrenoside R and S (1 and 2), and one new phenylpropanoid glycoside, ardicrephenin (3), along with five known compounds (4-8), were isolated from roots of Ardisia crenata. Their structures were elucidated on the basis of NMR spectroscopic data and chemical methods. Compounds 2-7 were evaluated for their cytotoxic activities against A549, MCF-7, HepG2 and MDA-MB-231 cell lines by MTT assay. Ardicrenin (6) showed significant cytotoxicity, with IC50 values of 1.17 ± 0.01, 1.19 ± 0.06, 3.52 ± 0.23, and 16.61 ± 1.02 μmol·L-1, respectively.
