| Abstract: | The single factor experiment and orthogonal experiment were used to optimize the process, using extractant concentration, solid-liquid ratio, microwave power and extraction time as the investigation factors, and the extraction rate of ursolic acid in Potentilla discolo as the assessment index. The optimum conditions for the process were as follows: 90% ethanol was used as the extractant, the ratio of raw material to extractant was 1:20, and the extraction time was 120 s at a microwave power level of 250 W. |
