Genus Monanthotaxis: a review on distribution, ethnomedicinal uses and phytochemistry.

Abstract

This article reviews the geographical distribution, ethnomedicinal applications, and phytochemistry of the genus Monanthotaxis Baill, tribe Uvariae of the family Annonaceae. The reviewed works of literature were collected from various electronic databases including Google Scholar, PubMed, Science Direct, The International Plant Names Index (IPNI), and Research Gate. During this review, ninety-eight species of the genus Monanthotaxis were found to be widely distributed in tropical Africa. Some of those species are used in folkloric medicine by various communities to manage diseases and disease conditions such as fever, vomiting, headache, stomach-ache, malaria, helminthiasis, and hysteria. In the past 44 years (1979 to 2023), one hundred and nineteen secondary metabolites with different biomedical potentials have been reported from this genus. The reported compounds are categorised into flavonoids, alkaloids, terpenoids, polyoxygenated cyclohexane, and cyclohexene derivatives, benzyl derivatives, cinnamic acid derivatives, and stilbenoids. Most of the reported compounds showed an array of bioactivities corroborating the use of some members of the genus in folkloric medicine.
