Pomegranate peels are a potential source of bioactive compounds which are known for their antioxidant and antimicrobial activities. The present work aims to study, the optimization of ultrasonic assisted extraction (UAE) method to obtain phenolic compounds from pomegranate peels using ethanol as a solvent. It further aims to investigate the effect of three independent variables such as solvent–solid ratio, extraction temperature and extraction time on the response variables such as total yield (TY), total phenolic content (TPC) and total flavonoid content (TFC) using response surface methodology (RSM). The results of RSM revealed the optimized conditions of the solvent-solid ratio, extraction temperature and extraction time as 16.09, 30°C and 17.8 minutes respectively, with the maximum yield of 14.20%, TPC of 140.61 mg GAE/ml extract and TFC of 2.96 mg RE/ml extract. The results were further validated under the same conditions using UAE and then compared with the thermostatic water bath extraction method (TWE).
