Moringa Olivera is one of the most important plants in earth in fields of nutrition and medicines, and has economic value. The main objectives of this study were to measure trace elements concentrations and calculate co-factor of some elements K, Ca, Fe, Cu and Zn. Five samples were taken from soil and leaves of Moringa Olivera from Alsamrab area, analyzed by X- ray florescence (XRF) to measure concentrations of trace elements, which are K, Ca, Mn, Fe, Cu, Zn, Pb, Br, Rb, Y,± Zr and Nb which has concentrations of (6786 1650, 26920 ± 1209, 1051.2 ± 902.57, 41800 ± 3994.997, 13.04 ± 1.890, 65.68 ± 11.932, 22.48 ± 5.266, 6.2 ± 1.235, 48.14 ± 7.87, 18.66 ± 1.088, 307.8 ± 55.91 and 19.54 ± 3.95 ppm), respectively. Comparison between Sudanese Moringa Olivera and African studies (Nigeria, Burkina Faso and Ghana) concentrate in Ca, K, Cu, Zn and Fe elements. Nigerian Moringa (303, 1.65, N.F., 3.33 and 13.85 ppm), respectively. Burkina Faso Moringa (2098, 1922, N.F., 5.4 and 28.3 ppm), respectively. Ghanaian Moringa (26.4, 21.7, 7.1, 13.7 and 175 ppm). The results showed significantly cofactor of K and Ca (5.6% and 2.9%). Moringa has a competitive characteristic with other Sudanese food (Mango, Baobab and Pumpkin).
