Phytochemical Characterization of Punica Granatum Peel and Assessment of its Extracts Antimicrobial Potency

Abstract

The present study was designed to characterize the phytochemical and antibacterial activity of punica granatum peel extracts (Aqueous-Ethanolic and Acetone) against standard bacteria strains Gram positive staphylococcus aureus and Gram negative Echerichia coli, pseudomonas aeruginosa using disc diffusion method. The results of phytochemical screening show that all extracts contain alkaloids, tannins , saponins and glycosides. The result of antimicrobial activity potency indicates that aqueous extract have excellent antibacterial activity against staphylococcus aureus and moderate activity against Echerichia coli while it was in active against Pseudomonas auruginosa. Aceton extract showed good antibacterial activity against Pseudomonas auruginosa and Staphylococcus aureus while it was in effective against Echerichia coli. Ethanolic extract possessed only partiall antibacterial activity against Pseudomonas aeruginosa
