Background & Objectives: Punica granatum is a non-productive form of a plant and is used for the treatment of diseases in traditional medicine. In this study, we evaluate the antibacterial activity and the total phenol compounds of Punica granatum.
Materials & Methods: Disk and well diffusion methods and MIC were used to evaluate the antibacterial activity of hydro-alcoholic extract on S. aureus and E. coli compared to standard commercial antibiotic disks. Measurement of phenol compounds were performed by Seevers and Daly colorimetric methods (Folin-ciocalteu indicator).
Results: 35 and 29 mm inhibition zones in S. aureus and 22 and 17 mm inhibition zones in E. coli were shown by disk and well diffusion method, respectively. Also, 7.8 mg/ml concentration of extract showed the MIC points for two bacteria. Phenol compound of extract was 233.15±5.1 mg/g of extraction.
Conclusion: Antibacterial effect of Punica granatum compared to antibiotics indicates the strong activity against examined bacteria. Extensive antibacterial study of Punica granatum is suggested
