Introduction
Moringa oleifera Lam. (Family Moringaceae) is renowned for its diverse medicinal properties, including its traditional use in water purification and treatment of eye infections. Previous studies have highlighted the antimicrobial potential of various parts of the plant, including the roots and seeds. This research aims to evaluate the antimicrobial activity of the leaf extract of Moringa oleifera against a range of bacteria, specifically Gram-positive, Gram-negative, and acid-fast bacteria.
Antimicrobial Activity of Moringa Oleifera Leaf Extract
The study assessed the antimicrobial properties of ethanolic extracts of Moringa oleifera leaves against six bacterial strains: Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Sarcina lutea, Escherichia coli, and Mycobacterium phlei. Using a disc diffusion assay, the results demonstrated significant antimicrobial activity, with varying levels of effectiveness. The average zones of inhibition indicated that the leaf extract was most effective against E. coli, B. subtilis, and M. phlei, with inhibiting effects observed in the other bacteria as well. The researchers suggested that the observed antimicrobial activity could be attributed to specific antimicrobial compounds present in the leaf extract, which they are currently in the process of isolating.
Conclusion
The findings of this study underscore the potential of Moringa oleifera leaf extract as a source of natural antimicrobial agents. The significant antimicrobial properties exhibited against various bacteria highlight its potential applications in the field of medicine and agriculture. Further research to isolate and identify the specific antimicrobial substances is warranted, as it could lead to the development of new therapeutic agents and natural preservatives. The support from C.S.I.R and contributions from the Division of Microbiology at Jadavpur University have been instrumental in facilitating this research.
