This study was shaped to discover the antimicrobial, antioxidant and mineral profile of Moringa oleifera leaves extracts. The leaves crude extract was fractionated into different fractions using solvents of varying polarity. DPPH and FRAP methods were used to evaluate the antioxidant capacities of the extract fractions. DPPH scavenging activities were found in the range of 44.6 to 62.04% whereas the reducing power was in the range of 1.4 to 1.85mg/ml for ether and methanolic extracts respectively. Total phenolic contents (TPC) and total flavonoid contents (TFC) were also calculated and were found 284.66 ppm and 85.12 for methanolic and ethanolic extracts respectively. Antimicrobial analysis was completed against two fungal strains Aspergillus niger and Aspergillus flavus and bacterial strains Escherichia coli and Bacillus subtilis using Rifampicin and Terbinafine as control. ZID and MIC values were calculated. The analysis of mineral profile showed rich amounts of important minerals, in which the value for potassium was found to be greatest (17.12 ppm). The results of antioxidant and antimicrobial assays revealed that the plant leaves exhibited potent use to sustain healthy life.
