Abstract

The present disclosure provides an ultrasonic-microwave synergistic extraction method of total saponins in beautiful millettia root, comprising the following steps: S1, material treatment, S2, cold soaking, S3 enzymatic hydrolysis, S4 extract extraction, and S5 ultrasonic-microwave synergistic extraction. The extraction method of the present disclosure extracts relatively high content of total saponins, and has relatively high yield of saponins and low content of impurities, and each step acts synergistically to solve the problems of relatively low total saponin content, more impumayrities and bubbling in the extraction process.
