| Abstract | ||||
| THE CHEMICAL composition and antimicrobial activity of two …. essential oils extracted from the seeds of Moringa oleifera (MO) and Moringa peregrina (MP) against Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Pseudomonas aeruginosa, klebsiella pneumoniae, Salmonella typhi, Escherichia coli and Shigella flexneri strains were investigated. Antibacterial diffusion method was used, GC-MS analysis was done to the most effective oil and TEM was done to detect the internal effect on the highly affected bacteria. MO essential oil was the most effective and Ps. aeruginosa was the highly affected bacterial strain. GC-MS analysis showed that MO essential oil contains several fatty acids especially oleic acid, 6-Octadecenoic acid (11.27%). This acid could rupture the cell membrane of the bacteria and release all internal content as detected by TEM. In conclusion, MO essential oil may be further developed as a natural promising antibacterial agent. Future studies of synergism and compatibility may potentiate the antimicrobial activity. | ||||
