Medicinal uses, chemical constituents and biological activities of Rumex abyssinicus: A Comprehensive review

Abstract

Rumex abyssinicus is a valuable medicinal plant species that is native to tropical Africa. Traditionally, R. abyssinicus is used to treat different disease such as, liver diseases, hepatitis, malaria, scabies, blood pressure, jaundice, wound and pneumonia. The purpose of the current study was to review the literature on the ethnomedicinal uses, chemical constitutes and biological activities of R. abyssinicus in an attempt to create information for future studies aimed towards exploring the therapeutic ability of the species. A scientific search engines, namely Google Scholar, PubMed, Scopus, Science Direct and Web of knowledge for the search terms: Rumex abyssinicus, ethnomedicinal studies, phytochemical investigations, and pharmacological activities were undertaken. The search strategy included all articles with descriptors that were available until December 30, 2021. Only published works in English have been used on this study. The data was collected using textual descriptions of the studies, tabulation, grouping, and figures. The principal phytochemicals of R. abyssinicus are anthraquinones, flavonoids, terepenoids and phenolic compounds. The in vitro and in vivo studies on the crude extracts and compounds of R. abyssinicus showed antibacterial, antioxidant, anticancer, anti-inflammatory, antifungal, wound healing, antialzeimer’s and hepatoprotective activities of it. R. abyssinicus afforded drug leads such as helminthosporin (4) with anti-alzheimer and physicon (3) with antifungal and antioxidant activity. R. abyssinicus have traditionally been used to cure a variety of diseases. Pharmacological actions of phytochemicals were shown to be promising. Despite this, further studies on crude extracts and promising compounds are needed to find new drug candidates.
