A Review of the Ethnomedicine, Phytochemistry and Biological Activities of the Genus Parinari

Parinari is a genus of woody medicinal plants with expansive ethnomedicinal uses. While extensive data are available for several members of this genus, this information is generally scattered. This review therefore crystallizes major reports relating to the ethnomedicinal uses, phytochemistry, and biological activities of this genus for easy accessibility. The rich therapeutic applications of this genus include their use as antimalarial, antidiabetic, anti-inflammatory, antimicrobial, anti-snake venom, and anticancer agents. However, the overarching biological theme for this genus appears to be their application in treating infection and infection-related diseases. These bioactivities have largely been attributed to molecules isolated from this genus and categorized under; kaurene-type diterpenoids, triterpenoids (ursane, oleanane, and lupane types), flavonoids, steroids, and phenolic compounds. While data is available for most parts of the plants, the stem appears to be the most used part. Given the varied medicinal uses of this genus, and yet the scarcity of information on many Parinari species, studies on the ethnomedicine, phytochemistry, and biological activities that fully explore the medicinal potential of this genus for drug discovery are critical. These include the need for comprehensive phytochemical profiling to uncover novel compounds, detailed studies on mechanisms of action, and translational research to validate clinical efficacy. Additionally, comparative ethnobotanical studies, standardization of extraction methods, and sustainable harvesting practices are critical to fully realizing the medicinal potential of Parinari species.
