Abstract: The present study was carried out to investigate the comparative evaluation of antimicrobial properties of normal and formalin treated mango peel and flesh. The pure and chemical free mangoes are separated into two groups, normal and formalin treated. Then upon ethanol extraction zone on inhibition, MIC and MBC are determined. The test was carried out against six pathogenic bacteria using agar disc diffusion method. The extracts exhibited reasonable antibacterial activities against two gram positive (Bacillus cereus, Staphylococcus aureus) and four gram negative (Escherichia coli, Shigella dysenteriae, Agrobacterium species, Shigella sonnei) pathogenic bacteria. In comparison between peels and fleshes it is observe that fleshes contain more antibacterial action than peel and between normal and formalin treated extract, the later shows maximum activity. The present study clarifies that treatment with formalin elevates antimicrobial potential of mango extract.
