MINIMUM INHIBITION AND BACTERICIDAL CONCENTRATIONS OF THE PLANT MORINGA OLEIFERA EXTRACTS AGAINST THE BACTERIA ESCHERICHIA COLI AND STAPHYLOCOCCUS AUREUS

This study aimed at assessing the MICs (Minimum Inhibitory Concentrations) and MBCs Bactericidal of methanolic extracts from 4 different parts (leaves, seeds, stem, roots) plant Moringa oleifera against bacteria E. coli S. aureus. Phytochemical profile each extract has been determined using LC/MS analyses. Microbial analyses were done 96-wells plate method. Results showed that four on plants contain heterosides glucosinolates. Iridoids found in leaves, stem roots. Flavonoids leaves stem. Phenolic acids only carboxylic The abundance number identified compounds a given class varied one part to another. with respect microorganism plant. With coli, 0.009 (leaves) 1.25 mg/mL (seeds), 0.156 2.5 (seeds stem). aureus, (stem 0.039 (leaves roots), 0.078 (stem). bactericidal or bacteriostatic properties depending considered. Against roots whereas seeds was bactericidal.
