In this study, the effect of deep eutectic solvent on the extraction of phenolic compounds (TPC) from pomegranate peel was investigated. The extraction was performed using an ultrasound bath. The results were compared with conventional extraction. In addition, different solvents (such as water and ethanol) were also examined to determine the efficacy of deep eutectic solvents. The highest TPC values by ultrasound assisted extraction method were found as 154.7, 171.2 and 195.1 mg GAE/g dry matter for water, deep eutectic solvent and ethanol-water (50:50 (v/v)), respectively. The difference in TPC values between ethanol-water and deep eutectic solvent was statistically insignificant. The shortest extraction time was obtained using deep eutectic solvent for ultrasound assisted extraction. The TPC values obtained during conventional extraction were lower compared to that of ultrasound extraction.
