Abstract:
:A new cycloartane triterpene bisdesmoside, soulieoside T (1), and one known compound, oleanolic acid (2), were isolated from the ethanolic extract of the rhizomes of Actaea vaginata. Their structures were elucidated by spectroscopic methods and by comparison with data reported in the literature. Compound 1 was evaluated for cytotoxic activities against three human cancer cell lines.
