Abstract: Lippia multiflora Moldenke leaves are used for the preparation of tea infusions in traditional medicine. In this study, the mineral composition of the leaves of the long-leaf morphotype of Lippia multiflora, collected from different cities of Ivory Coast, and their infusions were determined by Atomic Absorption Spectroscopy (AAS). The results showed that calcium (8231.17±0.5-10823.66±0.02 mg.kg-1), potassium (2740.00±0.2-7949.87±0.41 mg.kg-1), magnesium (3414.33±0.15-4731.00±0.15 mg.kg-1) and sodium (1046.76±0.45-1190.33±0.4 mg.kg-1) were the most predominant macroelements in the leaves, compared to the microelements Fe (62.50±0.0-142.00±0.0 mg. kg-1), Mn (21.67±0.0-54.33±0.02 mg.kg-1), Zn (30.17±0.00-41.33±0.00 mg.kg-1) and Cu (16±0.00-32.17±0.0 mg.kg-1). In the infusions, the order of magnitude of the minerals was: Na > K > Ca > Mg > P > Zn > Mn > Cu > Fe. However, the mineral contents of the infusions were very low compared to their respective daily doses recommended by the World Health Organization; thus demonstrating a safe consumption of this herbal tea.
