Research Progress on Chemical Constituents and Pharmacological Activities of Menispermi Rhizoma

Menispermi Rhizoma, the rhizome of Menispermum dauricum DC., is a traditional Chinese medicine, which has the effect of clearing away heat and detoxification, dispelling wind, and relieving pain. It is often used in the treatment of sore throat, enteritis, dysentery, and rheumatism. The chemical constituents of M. Rhizoma mainly include alkaloids, phenolic acids, quinones, cardiotonic glycosides, and so on. Modern pharmacological studies have proved that M. Rhizoma has the effects of anti-tumour, anti-inflammation, anti-oxidation, bacteriostasis, cardio-cerebrovascular protection, anti-depression and anti-Alzheimer’s disease. In recent years, the chemical constituents of M. Rhizoma have been found continuously, and the pharmacological studies have deepened gradually. This paper reviews the research progress on the chemical composition and pharmacological effects of M. Rhizoma, to provide a basis for further research and development of its medicinal value.
