Abstract: 
Natural phytochemicals isolated from medicinal plants acts as inhibitors for pathogenic microorganisms which causes contagious diseases to human beings. The present study was done to explore the antimicrobial activity of aqueous and aqueous-ethanol extract of Punica grantum leaves. The phytochemical analysis of both the extracts revealed the presence of total phenolics & flavonoids at varied concentration. The antimicrobial activity of the extracts was carried out by disc diffusion method. Both the aqueous and aqueous-ethanol extract showed the antimicrobial activity against S. aureus, Shi. dysentriae & Shi. flexineri. The antimicrobial activity of the Punica grantum leaves extracts could be attributed by the presence of phenolics and flavonoids.
