Comparative study of anti bacterial activity of barks, leaves and flesh extracts of Moringa oleifera L
Journal Title: International Journal of Allied Medical Sciences and Clinical Research - Year 2014, Vol 2, Issue 3
Abstract
In the present study, comparative anti bacterial activity of barks, leaves and flesh extracts of Moringa oleifera L was evaluated with different pathogenic gram positive and gram negative microorganisms. Twelve extracts of barks, leaves and flesh of Moringa oleifera L were prepared with four solvent such as alcohol, ethyl acetate, benzene and acetone. The combinations of extracts were prepared in 1:1 ratio. Antimicrobial activity was evaluated by agar disc diffusion method. All the extracts showed the anti microbial activity against the microorganisms. According to the zone of inhibition observed in the entire agar plates, the ethyl acetate extracts of Moringa oleifera (Leaf and Bark), (Bark and Flesh) showed maximum zone of inhibitions 20 mm, 17 mm against Micrococcus luteus respectively. The alcoholic extract (Leaf and Flesh) showed zone of inhibition 19 mm against Bacillus Subtilis and (Bark and Flesh) extract showed zone of inhibition 18 mm against the pseudomonas aeuroginosa. The acetone extract of Moringa oleifera showed lowest antimicrobial activity when compare to the other solvents extracts. From these studies concluded that, ethyl acetate extract of Moringa oleifera showed good antimicrobial activity than other extracts. Further the analysis of active ingredients present in this plant responsible for antimicrobial activity is important for the further development of new drugs.
