Abstract: The ultrasonic-assisted extraction of total polyphenols from pomegranate peels using 80% acidified ethanol as the extractant was optimized by orthogonal array design method. The highest extraction efficiency of total polyphenols from pomegranate peels, 14.06 mg/g, was obtained after a single extraction at 30 ℃ and a solid-to-liquid ratio of 1:20 (g/mL) based on ultrasonic treatment for 20 min at a power level of 100 W.

Key words: ultrasonic-assisted extraction, total polyphenols, pomegranate peels
