The Progress in Applications of Ultrasonic Technique in Extraction of Polyphenols from Plant

In order to promote the application of ultrasonic technique in plant polyphenols, this paper summarized the application of ultrasonic technique in the determination and extraction of plant polyphenols, and introduced the method to optimize technological parameters of ultrasonic extraction in extraction of plant polyphenols. It pointed out that the ultrasonic technique was widely used in the determination of plant polyphenols, as well as in the extraction of total polyphenols, tannin, flavonoids and the monomer of polyphenols. The ultrasonic power and frequency, ultrasonic time and temperature, extracting solvent and ratio of solid to liquid were the main factor influencing the extraction efficiency of polyphenols, using orthogonal design experiment and response surface design experiment can improve the extraction efficiency. Ultrasonic technique is suitable for the extraction of plant polyphenols, there would be broad application prospects in the field.
