Abstract
A new cycloartane-type triterpene glycoside, namely soulieoside M (1), and one known compound, beesioside I (2), were isolated from the ethanolic extract of the rhizomes of Souliea vaginata. Their structures were determined spectroscopically and compared with previously reported spectral data. Compounds 1 and 2 were evaluated for their cytotoxic activities against three human cancer cell lines.
