Evaluation of Antibacterial Activity and Total Phenol Compounds of Punica granatum Hydro-Alcoholic Extract

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.
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).
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.
Antibacterial effect of Punica granatum compared to antibiotics indicates the strong activity against examined bacteria. Extensive antibacterial study of Punica granatum is suggested.
