Abstract
Seven new pentacyclic triterpenoid saponins, named dianversicosides A-G (1-7), together with nine known compounds, were isolated from the aerial parts of Dianthus versicolor. The structures of 1-7 were elucidated on the basis of spectroscopic data and chemical evidence. The absolute configuration of the 3-hydroxyl-3-methylglutaryl (HMG) group in 1-4 was ascertained by chemical analysis combined with a chiral HPLC method. Cytotoxic activities of the isolated compounds were evaluated against a small panel of cancer and other cell lines.
