| Abstract: | In this paper, the design process of ultrasonic power extraction system circuit of phytochemical active constituents was introduced. The power extraction system circuit is composed of four parts: voltage transformation (commutation and filter) circuit, signal generating circuit, driving circuit and matching circuit. At last, the application of ultrasonic power extraction system circuit was discussed. The extraction of puerarin was made for 20 minutes and the one time extraction rate reached 98.3%. |
