Abstract

In this work, ten medicinal and nutritional leaves samples of Hibiscus sabdariffa Linn imported from Mali and Burkina Faso in Cote d’Ivoire and sold on the market were collected. The analysis of these plants using Energy Dispersive X Ray Fluorescence Technique showed medicinal roles of some elements of this plant in the human body. Leaves of this plant were analyzed for their trace element contents. The plant samples were found to contain essential chemical elements such as Ca, K, Na, Cl, Mg, Mn, Fe, Zn and Br which are well known for their important roles in in human body (herbal drugs). The elemental concentrations in different in the calyxes of this plant and their biological effects are discussed.
