A review of plant characteristics, phytochemistry and bioactivities of the genus Glechoma
2021
Plants of the genus Glechoma have been abundantly used for thousands of years in China as folk treatments for cholelithiasis, urolithiasis, inflammation, and other conditions. This review discusses the potential application of Glechoma as an herbal medicine. The plant characteristics, ethnobotanical uses, phytochemistry, and pharmacological activities of Glechoma are summarized as a guide for phytochemical and pharmacological investigations. Various search engines including SciFinder, Google Scholar, Scopus-Elsevier, Medline, Web of Science, and China National Knowledge Infrastructure were searched for publications on Glechoma using relevant keywords. Additionally, local records, books, and non-English journals were screened up to October 2020. The phytochemistry of several Glechoma plants has been systematically studied, and over one hundred different compounds have been isolated and identified. Terpenoids, flavonoids and polyphenols are the major secondary metabolites. Crude extracts and isolated compounds have been shown to exhibit various pharmacological activities including prevention of nephrolithiasis, anti-inflammatory, analgesic, anticomplement, antimicrobial, antioxidant, depigmenting, anticancer, and antiviral activities, among others. Glechoma species have been used as folk medicine to treat various diseases and have diverse biological activities, making them valuable starting materials for drug development. However, in most cases the pharmacological mechanisms, pharmacokinetics, toxicology, safety, and possible interactions with other drugs remain to be determined.
