Abstract

Abstract: Ethnopharmacological relevance: Cynanchum paniculatum (Bunge) Kitag. ex H. Hara ( C. paniculatum ), is a broadly used traditional medicinal plant by East Asians. The roots and rhizomes of this herb were named 'Xu-Chang-Qing' since the Qin or Han Dynasty (B.C.221-220) in China. It is pungent and warm in nature and associated with the liver and stomach meridians. Moreover, the efficacy of this herb are dispelling wind, resolving dampness, relieving pain and itching. It is used for treating the onset of rheumatic arthralgia, stomachache, toothache, lumbago, soft tissue injury, rubella and eczema. Aim of the study: The purpose of this paper is to provide a systematic review about the botany, traditional uses, phytochemistry and pharmacology of C. paniculatum on the strength of the studies in the past two decades. Materials and methods: A comprehensive search on previous literature was conducted on databases such as Web of Science, Pubmed, Sciencedirect, American Chemical Society (ACS), Google scholar and China national knowledge internet (CNKI). The search was based on the botany, traditional uses, phytochemistry and pharmacology of C. paniculatum . The key search words were ' Cynanchum paniculatum ' and 'Radix Cynanchi Paniculati'. In addition, some published books were searched for more information on the herb. Results: Over 150 compounds have been isolated and identified from C. paniculatum, including C21 steroids, volatile oils, carbohydrates and phenanthroindolizidine alkaloids. Extensive pharmacological activities of the extracts or compounds of C. paniculatum in vivo and in vitro were confirmed including anti-inflammatory, anti-nociceptive, sedative antiviral, antitumor, neuroprotective, treating snake bites, immunomodulatory, anti-radiation, vasodilatory, acaricidal potentials and anti-adipogenic activities. Conclusions: In this paper, the botany, traditional uses, phytochemistry and pharmacology of C. paniculatum were reviewed. This herb has long been used as traditional medicine. It was reported with numerous chemical ingredients and various pharmacological activities with anti-inflammatory, antitumor, neuroprotection, etc. In the future, C. paniculatum still needs further study, such as identifying the active compounds, clarifying the pharmacological mechanisms, discussing quality and safety.
