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
Extracts from the roots and rhizomes of black cohosh (Cimicifuga racemosa) are widely used as dietary supplements to alleviate menopausal symptoms. State-of-the-art quality control measures involve phytochemical fingerprinting of the triterpene glycosides for species identification and chemical
We investigated the effect of the phytoestrogen cimicifugoside, one of the pharmacologically active ingredients of the medicinal plant Cimicifuga racemosa (black cohosh) that has been used to treat many kinds of neuronal and menopausal symptoms, such as arthritis, menopausal depression, and nerve
The occurrence of vasomotor symptoms in women is directly related to deficiency of estrogen, which occurs as a result of natural or surgical menopause. Hot flushes may also be a major problem for patients with a history of breast cancer, as they may result directly from cancer treatment
A method to directly identify triterpene glycosides using reversed-phase liquid chromatography with positive atmospheric pressure chemical ionization mass spectrometry (LC/(+)APCIMS) was developed. Based on the analysis of the molecular weight, fragment ions, selected ion chromatograms, a number of
BACKGROUND
Black cohosh (Actaea racemosa L.), Ranunculaceae, thrives in temperate climates east of the Mississippi River in the USA. It is economically important to the Appalachian region where it is wild harvested, but it has resisted most efforts at deliberate cultivation. Black cohosh has been
