Cytotoxic Cycloartane Triterpenoid Saponins from the Rhizomes of Cimicifuga foetida
Abstract
To enrich the bioactive cycloartane triterpenoid glycoside named actein and find out more cytotoxic cycloartane triterpenes, a phytochemical study of Cimicifuga foetida was conducted. 113 g (0.17%) actein was purified by recrystallization while eight cycloartane-type triterpenes (1-8) were isolated from the mother liquid. The chemical structures of new compounds (1-4) were elucidated by 1D and 2D NMR and HRESIMS spectroscopic analyses. Moreover, new compounds showed moderate and broad-spectrum cytotoxicity against 5 human cancer cell lines with IC50 values ranging from 4.02 to 15.80 μM.
Keywords: Cimicifuga foetida; Cycloartane triterpenoid saponins; Cytotoxic activity.
