Tragia L. Genus: Ethnopharmacological Use, Phytochemical Composition and Biological Activity

Tragia L. is a genus of plants belonging to the Euphorbiaceae family with worldwide intertropical distribution, composed of more than 150 species. In this literature review, 26 species of the genus used as medicinal plants were found, mainly in East Africa and the Indian subcontinent, with a variety of uses among which antibacterial, anti-inflammatory, anticancer and reproductive health are most common. Research has been done on a few of the species, mostly those of the Old World, with emphasis on four of them: Tragia involucrata Linn., Tragia spathulata Benth., Tragia benthamii Baker and Tragia plukenetii Radcl.-Sm., confirming several ethnomedicinal claims. Moreover, a variety of active phytochemicals have been isolated, mainly ethers, hydrocarbons, flavonoids and sterols. There is ample field for the evaluation of the activity of Tragia extracts and essential oils and the identification of their active compounds, particularly of the New World species, for which there is still very little research.

Automated summary

Tragia, a genus of plants in the Euphorbiaceae family, has medicinal uses such as antibacterial, anti-inflammatory, anticancer, and reproductive health. Research has confirmed ethnopharmacological claims for some Old World species, but there is still limited research on New World species. Phytochemicals like ethers, hydrocarbons, flavonoids, and sterols have been isolated from Tragia plants.
