Medicinal plants contain mineral elements that are vital therapeutically. In this study, concentration levels of Ca. Cr and Cu in Tagetes minuta, Senna didym obotrya. Bauhinia torneutosa, Prunus africana, Eucalyptus saligna, Bidens pilosa, Aloe secundiflora, Caesalpinia volkensii, Anthocleista grandiflora and \' emonia lasiopus were determined. Leaves and stem barks of T. m iuuta had the highest mean levels of Cu (0.25=0.01 mg/Kg ), while the least was in stem bark of S. didyuiobotrya at levels of O.O1±O.OO mg/Kg. Stem barks of S. didymobotrya had the highest mean levels of Cr (1.60±0.01 rug/Kg). Leaves of S. didymobotrya had the lowest mean levels of Cr (0.49=0.02 rug/Kg). Levels of Ca in these medicinal plants ranged from 0.21-78.00 mg/Kg. Concentration levels of minerals in these medicinal plants may be responsible for their medicinal properties.
