| Abstract | ||
| Ethanolic and aqueous extracts of Punica granatum L. peels were prepared and tested for antibacterial activity against Escherichia coli and Pseudomonas aerogenosa as gram negative bacteria and Staphylococcus aureus as gram positive bacteria. The suitability of extracts for topical pharmaceutical preparations was attempted by formulation of extracts into simple ointment and hydrogel pharmaceutical dosage forms. The antibacterial activity was assessed by agar well diffusion method using four different concentrations for both extracts include (100, 10, 1, 0.1mg/ml). Ethanolic and aqueous extracts showed antibacterial activity against Staphylococcus aureus, with lowest inhibition zone of 12mm at 0.1mg/ml. The same result was obtained for ethanolic extract against E. coli, whereas, aqueous extract showed 9mm zone of inhibition. The lowest inhibition zone against Pseudomonas aerogenosa,was 10mm at 0.1mg/ml of ethanolic extract and 1mg/ml of aqueous extract which showed resistance at 0.1mg/ml. From this it is concluded that both extracts have inhibitor effect on the growth of both gram positive and negative bacteria and ethanolic extracts exhibited higher degree of antibacterial activity as compared to aqueous extract. In present study, simple ointment containing (10%w/v) of ethanolic extract and hydrogel containing (10%w/v) of aqueous extract were prepared successfully. | ||
