The purpose of this research work is to investigate the elemental composition and antioxidant potentials of Spondias mombin (leaf, root and stem bark) at concentration of 10, 20 and 5mg/ml. using different conventional laboratory methods, also to determine the antioxidant potentials of Spondias mombin. The element present are Sodium (Na), Calcium (Ca), Magnesium (Mg), Zinc (Zn), Iron (Fe), Lead (Pb), Copper(Cu), Manganese (Mn), Potasium (K) and Phosphorus (P).it was observed that all elements were present at appreciable quantity. It was observed that the highest and lowest quantity were found in Zinc (20.34) and Cu (1.22) for the leaf extract, Potasium (24.98) and (2.14) for stem bark, Calcium (29.35) and Pb (2.91) for the root extract. Pb has minimal quantity in all parts of Spondias mombin extract. P value< 0.0001, Significantly different standard deviations (P < 0.05).The antioxidant composition are FRAP, DPPH, Fe2+,ABTS, H2O2 and superoxide.
