Five phenylpropanoid esters, caffeoylglycolic acid, 2-caffeoylpiscidic acid (cimicifugic acid D), 3,4-dihydroxyphenacyl caffeate (petasiphenone), 3,4-dihydroxyphenyl-2-oxopropyl isoferulate (cimiciphenol) and 3,4-dihydroxyphenacyl isoferulate (cimiciphenone) were isolated from a commercially
Caffeic acid derivatives occurring in black cohosh [Cimicifuga racemosa (L.) Nutt., Actaea racemosa (Ranunculaceae)], some of which may have pharmacological activity, were analyzed using high-performance liquid chromatography (HPLC) electrospray ionization tandem mass spectrometry (ESI-MS/MS) with
A new cyclic guanidine alkaloid, cimipronidine (1), together with the known compound fukinolic acid (2), was isolated from the n-BuOH-soluble fraction of Cimicifuga racemosa roots that showed 5-HT7 receptor binding activity. Structure elucidation of 1, a minor constituent, presented unique
Caffeic acid, fukinolic acid as well as cimicifugic acids A, B, E and F isolated from the rhizomes of Cimicifuga racemosa (Ranunculaceae) inhibited the activity of neutrophil elastase (EC 3.4.21.37) in a dose-dependent manner. An IC50 of 93 mumol/L was determined for caffeic acid and 0.23 mumol/L
The roots/rhizomes of Cimicifuga racemosa L. (Nutt.) (black cohosh) have traditionally been used to treat menopausal symptoms through an unknown mechanism of action. In an effort to determine if black cohosh had additional health benefits, methanol extracts were investigated for their potential to
Black cohosh (Actaea racemosa L. [syn. Cimifuga racemosa L.]) extracts (BCE) are marketed worldwide for the management of menopausal symptoms. However, recently more than 75 cases of hepatotoxicity associated with black cohosh ingestion have been reported. While these cases have not been fully
A new lignan, actaealactone (1), and a new phenylpropanoid ester derivative, cimicifugic acid G (2), together with 15 known polyphenols, protocatechuic acid, protocatechualdehyde, p-coumaric acid, caffeic acid, methyl caffeate, ferulic acid, ferulate-1-methyl ester, isoferulic acid,
From the 80% acetone extract of "Cimicifugae Rhizoma" (a mixture of Cimicifuga dahurica and C. heracleifolia used medicinally), seven new fukiic acid derivatives (1-7) and a new phenylethanoid derivative (8) were isolated along with eight known compounds (9-16). Fukinolic acid (9) and cimicifugic
Hydroxycinnamic acid esters of fukiic acid and piscidic acid were isolated from a 50% ethanolic extract obtained from the rhizomes of Cimicifuga racemosa (Ranunculaceae). Besides 2-E-caffeoylfukiic acid (fukinolic acid), 2-E-feruloylfukiic acid (cimicifugic acid A), 2-E-isoferuloylfukiic acid
