The structures of two new cycloartane-type saponin constituents of the roots of Cimicifuga foetida were established by the interpretation of spectroscopic data as 2'-O-acetylactein (1) and 2'-O-acetyl-27-deoxyactein (2), respectively. Also isolated were the known compounds actein, 27-deoxyactein,
An RP-HPLC method with evaporative light scattering detection (ELSD) was developed for the analysis of terpene compounds in traditional Chinese medicine. Actein, 27-deoxyactein and cimicifugoside in a typical Chinese medicine of Cimicifuga foetida L. were quantitatively analyzed. Comparing ELSD with
OBJECTIVE
To find new active constituents from Rhizome of Cimicifuga foetida.
METHODS
Various column chromatographic techniques were employed for isolation and purification. The structures were elucidated on the basis of spectral and chemical evidences.
RESULTS
Four triterpenoid compounds were
