Supersonic extraction process of glycyrrhizia polysaccharide(GPS) was examined by orthogonal experiments. The optimized supersonic extraction process was obtained and mathematical simulation based on the supersonic extraction was established. The optimized condition for extraction of GPS is as follows: supersonic treatment time is 3.5 h, supersonic treatment temperature is 81℃, liquid-solid ratio is 10 mL/g, number of times of extraction is 1. Under the optimized condition, the extraction rate of GPS is 5.40%, purity is 39.95% and the relative deviation of repeated experiments is 2.54%.
