Estimation of antimicrobial activity of green mango ( mangifera indica L. ) Extract on the Growth of Bacteria

Abstract

Abstract: Alternative herbal medicine has been used to treat various infections in human as well as in animal, natural plants contain phytoconstituent having similar chemical properties as of synthetic antibiotics ,due to that, the aim of this study was to investigate the biological properties of green mango (Mangifera indica L.). The extraction of active phytoconstituent of green mango was done by the infusion method. Antimicrobial activity was carried out by agar well diffusion method against two species of gram-positive bacteria and five-gram negative bacteria, at different concentrations 5%,10%,50 %. The extract of concentration 5% has shown >2 mm zone of inhibition and after further screen can be considered as minimum inhibitory concentration (MIC). The mean zone of inhibition produced inhibition area range between 5mm and 26 mm. The inhibition zone of 26 mm for streptococcus has showed the highest zone of inhibition area. The infusion extract of green mango (Mangifera indica L.) showed a good inhibitory effect against almost the tested strains. Green mango extract can serve as a potential antimicrobial agent for use in the food industry and pharmaceutical manufacturing.
