Ethnopharmacology, Phytochemistry, and Pharmacology of Pyrethrum tatsienense (Bureau & Franch.) Ling ex C. Shih: A Comprehensive Review

Background: Pyrethrum tatsienense (Bureau amp; Franch.) Ling ex C. Shih (PTLCS) belongs to the family Compositae, which is a perennial medicinal plant mainly distributed in the Qinghai-Tibet Plateau of China. This review provides a comprehensive summary of the ethnopharmacology, phytochemistry, and pharmacology of PTLCS. This review offers valuable references and guidance for researching PTLCS in depth. Methods: The related references of PTLCS were retrieved from an online database, such as Web of Science, Google Scholar, SciFinder, PubMed, SpringLink, Elsevier, Willy, CNKI, and so on. Results: PTLCS is widely reported for treating headaches, head injuries, traumatic injuries, anabrosis, impetigo, hepatitis, and other diseases in the medical field. Phytochemical research revealed that this plant contained flavonoid aglycones, flavonoid glycosides, xanthones, triterpenoids, coumarins, polyacetylenes, volatile oils, and other compounds. Meanwhile, PTLCS exhibited extensive pharmacological activities including anti-cardiac ischemia, anti-hypoxia, hepatoprotective, anti- inflammatory and analgesic, and antioxidant activities. Conclusions: PTLCS is widely used as a Tibetan medicine, which has a variety of chemicals with diverse bioactivities. Therefore, further studies are necessary to perform on the PTLCS to assay biological activities, discover their bioactive constituents, and reveal pharmacological mechanisms. This review may supply an important theoretical basis and valuable reference for in-depth research and exploitations of PTLCS.
