Abstract
Pomegranate seed was used as raw material and the influence of ultrasonic wave assisted extraction on yield of polyphenols was studied by single factor experiment and orthogonal experiment.And the process conditions were optimized and the optimum conditions were determined.The optimum extraction conditions were as follows,ultrasonic wave treatment for 25min at 50℃,ratios of material to liquid(solvent) 1∶18(g∶ml),ultrasonic power 200W.And under these conditions,yield of polyphenols is 4.65mg/g.Comparison study of ultrasonic wave assisted extraction with normal solvent extraction indicated that the previous method has the advantages of short-term,high efficiency and energy-saving.
