0.19/0.39 mg/ml. Variations in results among studies on pomegranate fruit peel extracts were recorded with
MIC determination. The values for MIC against S. aureus ranged from 0.62 to > 250 mg/ml4. The MIC
varied from 0.39–25 mg/ml against several strains of E. coli 4, 11, 12. The MIC values for test bacteria seemed to correlate with the total phenolic content found in the extracts. The total phenolic content of hot-water extracts
of fruit peels was the highest, followed by the ethanol and acetone extracts, respectively (Table 3). This showed that the solvent that is less polar (acetone) extracted less amount of total phenolic compounds. Polyphenols are hydrophilic phytochemicals and thus more hydrophilic extractants are better solvents for their recovery from plant4. Different results were found by Negi et al13 who used sun-dried and powdered pomegranate peels extracted with a Soxhlet extractor. They reported that the phenolic content of acetone, methanol, and water extracts of the peels was 52, 46.2, and 4.8%, respectively. Pomegranate
