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
In the present work, a fast and simple method for the separation and purification of triterpene saponins from Actaea racemosa was successfully established. Accelerated solvent extraction was used for defatting and extracting of the subaerial parts, giving a triterpene enriched crude extract. Size
A new cycloartane glycoside (1) was obtained from a minor triterpene fraction of the rhizome extract of Actaea racemosa (synonym: Cimicifuga racemosa) along with a known compound, cimigenol 3-O-beta-D-xylopyranoside. The structure of 1 was elucidated as
Six new cycloartane triterpene glycosides, (3',12beta)-O-diacetyl-cimigenol-3-O-beta-D-xylopyranoside (1), (4',25)-O-diacetyl-cimigenol-3-O-beta-D-xylopyranoside (2), 2'-O-acetyl-25-O-methyl-cimigenol-3-O-beta-D-xylopyranoside (3), 2'-O-acetyl-25-O-ethyl-cimigenol-3-O-beta-D-xylopyranoside (4),
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

Cycloartane triterpenoids, 2',24-O-diacetylisodahurinol-3-O-α-L-arabinopyranoside, 24-O-acetylisodahurinol-3-O-α-L-arabinopyranoside, 12β-hydroxy-25-anhydrocimigenol, cimigenol-12-one, 12β-hydroxy-15-deoxycimigenol, 2'-O-acetyl-24-epi-cimigenol-3-O-α-L-arabinopyranoside,
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
One new triterpene glycoside, cimiracemoside , and 14 known triterpene glycosides have been isolated from the rhizome extracts of black cohosh (Cimicifuga racemosa). On the basis of spectral and chemical evidence, the structure of the new compound was elucidated to be
Eight new triterpene glycosides named cimiracemosides A-H, respectively, and eight known triterpene glycosides were isolated from the rhizome extracts of black cohosh (Cimicifuga racemosa). The new compounds were determined by spectral data to be 21-hydroxycimigenol-3-O-alpha-L-arabinopyranoside
