Due to the complexity and variation of the chemical constituents in authentic black cohosh (Actaea racemosa) and its potential adulterant species, an accurate and feasible method for black cohosh authentication is not easy. A high-resolution accurate mass (HRAM) LC-MS fingerprinting method combined

Ester and amide derivatives of hydroxycinnamic acids are found in black cohosh (Actaea racemosa) and other Actaea plants. These two compound groups were evaluated for authentication of black cohosh dietary supplements. The hydroxycinnamic acid esters (HCAE) were profiled by ultra-performance liquid

What is the central question of this study? We investigated the effects of oestrogen and Cimicifuga racemosa on the stellate ganglion, cardiac noradrenaline pathway and Ca2+ -calmodulin-dependent protein kinase II in ovariectomized rats. What is the main finding and its importance? The right

OBJECTIVE Extracts of Black cohosh (Cimicifuga racemosa or CR) have been used for the treatment of climacteric complaints since decades. Efficacy, particularly concerning neurovegetative and psychic symptoms, has been proven in clinical trials. As active principle yet unknown substances with

We investigated the effects of Cimicifuga racemosa (CR) plant extracts on the changes in levels of the cerebral monoamines norepinephrine (NE), dopamine (DA), and serotonin (5-HT), the respective metabolites 3-methoxy-4-hydroxyphenylglycol (MHPG), 3,4-dihydroxyphenylacetic acid (DOPAC), and

As an extension of work on the recently discovered nitrogenous metabolites from Cimicifuga/Actaea species, three new guanidine alkaloids have been isolated and characterized from C. racemosa (syn. A. racemosa) roots. Of these, cyclo-cimipronidine (1) and cimipronidine methyl ester (2) are congeners
