Achyranthes bidentata Blume (Amaranthaceae): a review of its botany, traditional uses, phytochemistry, pharmacology, and toxicology

Abstract

Objectives Achyranthes bidentata Blume (A. bidentata) is a plant of Amaranthaceae family, and its root is the main medicinal part, named “Huai-Niu-Xi.” It is used to expel blood stasis through menstruation, tonify liver and kidney, strengthen muscles and bones, and induce diuresis. This review aimed to provide a systematic summary of botany, traditional uses, phytochemistry, pharmacology, and toxicology of A. bidentata. Methods The present review covers the literature survey. The data have been collected from various journals, books, and some of the electronic search via Internet-based information such as Web of Science, PubMed, Google Scholar, Google patents, CNKI, SpringerLink, online electronic journals, and ScienceDirect. Key findings So far, more than 270 metabolites have been isolated from A. bidentata, including terpenoids, steroids, alkaloids, flavonoids, and so on. Among them, terpenoids and steroids are the main metabolites. The extract and metabolites exert multiple pharmacological activities such as alleviating osteoarthritis effect, antiosteoporosis activity, neuroprotective effect, antidiabetic activity-associated complications, immunoregulatory activity, and so on. Summary Some traditional uses of A. bidentata need further in-depth studies to confirm. Similarly, the separation and screening of active compounds, as well as the corresponding molecular mechanisms of action of compounds, are also needed to be studied.
