A selective and sensitive LC-MS/MS method was developed and validated for the simultaneous determination of five constituents (cimicifugoside H-2, cimicifugoside H-1, 23-epi-26-deoxyactein, cimigenol xyloside and 25-O-acetylcimigenoside) of Cimicifuga foetida L. in beagle dog plasma. The
OBJECTIVE
To study cycloartane triterpenoid of Cimicifuga foetida and their osteoclast inhibition activity.
METHODS
The compounds were isolated and purified by normal and reversed phase column chromatographic methods. Structures were identified by spectroscopic analyses. Their osteoclast inhibition
A tetranor-cycloartane glycoside and two 9,19-cycloartane glycosides were isolated from the EtOAc-soluble fraction of the rhizome of Cimicifuga foetida. The structures of the compounds were determined to be cimilactone A (1), 25-O-acetylcimigenol 3-O-beta-d-xylopyranoside (2) and cimigenol
Two new cyclolanostanol glycosides, cimifoetiside IV (1) and cimifoetiside V (2) and two known compounds have been isolated from the aerial part of Cimicifuga foetida L. On the basis of spectral and chemical evidences, the structures of 1 and 2 were elucidated to be

Two new triterpenoids and a chromone glycoside, namely, 24-epi-cimigenol-3-one (1), foetinoside (2), cimifugin-4'-O-[6″-feruloyl]-β-D-glucopyranoside (3), together with 18 known compounds, were isolated from the rhizomes of Cimicifuga foetida L. collected in Guizhou Province, China. All of the
Two new cycloartane-type triterpene glycosides, namely cimicifoetisides A (1) and B (2), along with seven known compounds cimigenol, 25-O-acetylcimigenol, cimigenol 3-O-beta-D-xylopyranoside, 12beta-hydroxycimigenol 3-O-beta-D-xylopyranoside, cimigenol 3-O-alpha-L-arabinopyranoside,
Black cohosh has become one of the most important herbal products in the US dietary supplements market. It is manufactured from roots and rhizomes of Cimicifuga racemosa (Ranunculaceae). Botanical identification of the raw starting material is a key step in the quality control of black cohosh
