    This study was aimed at examining total phenolic content, flavonoids, antioxidant and antibacterial analysis of flowers sweet and sour of tow system extracts of Punica Granatum L. Antioxidant efficacies of extracts were evaluated by phosphomolybdenum method. The antimicrobial activity of extracts of was determined against three. The phenolic contents of ethanolic 80% sour extract (EASE) was founded to have the highest value 480 ± 0.02 mg AGE.g-1 DW and the lowest value in ethanoic sweet extract (ES) 118 ± 0.02 mg AGE.g-1 DW. The total antioxidant activity was also found to be highest with EASE extracts. For the antibacterial activity the extracts showed moderate activity. The most sensitive microorganism was Staphylococcus aureus (diameter of inhibition is 23 mm) showed in ethanolic 80% sweet extract at 20 mg/ml.
