Rhizomes of Actaea racemosa L. (formerly Cimicifuga racemosa) gained increasing interest as a plant-derived drug due to its hormone-like activity and the absence of estrogenic activity. According to the Current Good Manufacturing Practices guidelines and pharmacopeial standards, quality assessment of herbal starting materials includes tests on identity and substitution, as well as quantification of secondary metabolites, usually by HPTLC and LC methods. To reduce the laboratory effort, we investigated near-infrared spectroscopy for rapid species authentication and quantification of metabolites of interest...

Actein is isolated from the rthizomes of Cimicifuga foetida, which is a triterpene glycoside, displaying suppressive effects on breast cancer cells proliferation. However, the effects of actein treatment on liver injury, tending to cancer, have little to be known. Thus, the study is conducted to explore the role of actein in early liver cancer. Diethylnitrosamine (DEN) was used to induce liver cancer in mice followed by actein treatment at different concentrations. DEN caused steatohepatitis supported by fibrosis and inflammation, which were ameliorated for actein administration...

Actein is a triterpene glycoside isolated from the rhizomes of Cimicifuga foetida (Chinese herb "shengma") which could inhibit the growth of breast cancer cells. Nevertheless, the effect of actein on angiogenesis, which is an essential step for tumor growth and metastasis, has never been reported. Hence, this study aimed to investigate the in vitro and in vivo effects of actein on angiogenesis using human microvascular endothelial cells (HMEC-1), matrigel plug and tumor-bearing mouse models. Our results showed that actein significantly inhibited the proliferation, reduced the migration and motility of endothelial cells, and it could suppress the protein expressions of VEGFR1, pJNK and pERK, suggesting that JNK/ERK pathways were involved...

Botanical dietary supplements are increasingly popular for women's health, particularly for older women. The specific botanicals women take vary as a function of age. Younger women will use botanicals for urinary tract infections, especially Vaccinium macrocarpon (cranberry), where there is evidence for efficacy. Botanical dietary supplements for premenstrual syndrome (PMS) are less commonly used, and rigorous clinical trials have not been done. Some examples include Vitex agnus-castus (chasteberry), Angelica sinensis (dong quai), Viburnum opulus/prunifolium (cramp bark and black haw), and Zingiber officinale (ginger)...

Cimicifugae rhizoma has been widely used as a traditional herbal medicine to treat inflammation and menopausal symptoms. In this study, we found that some of the triterpenoidal saponins purified from the ethanol extract of Cimicifugae rhizoma dramatically induced histamine release. The structure-related induction of mast cell degranulation by them and the mechanism of action were determined. β-Hexosaminidase release in HMC-1 cells was increased in a concentration-dependent manner, with maximal 6.5- and 8.5-fold increases, by 200 μg/mL 24-epi-7,8-didehydrocimigenol-3-O-xyloside (comp 1) and cimigenol 3-O-beta-d-xyloside (comp 4) compared with those treated with phorbol 12-myristate 13-acetate and A23187 (PMACI), respectively...
