ABSTRACT

 The antimicrobial activities of Moringa oleifera leaves and seeds were tested in vitro using disc diffusion method. The minimum inhibitory concentration determination against human· pathogenic organisms was also determined. At the concentration of 1 00mg/ml, the extracts potential activity against: Pseudomonas aeruginosa, Salomone/la typhi, Candida albican, Staphylococcus aureus and Escherichia coli were tested. The ethanolic extracts· of the leaves and seed exhibited inhibitory effect on Salomonella typhi, Staphylococcus aureus and Escherichia coli respectively. The zones of inhibition for ethanol extracts of leaves ranged from 12mm-20mm while that of seeds ranged from 9mm-l5mm. The aqueous extract for leaves and seed ranged from 7mm-10mm and 8mm-1 lmm. The consequences of this investigation suggest that the leaves and seeds of Moringa oleifera can be used to discover antimicrobial agent for developing new pharmaceuticals to control human pathogenic organisms responsible for illness.
