| 中文摘要: |
| 采用单因素实验与正交实验法结合，以提取剂浓度、固液比、微波功率、微波提取时间为考察因素，以熊果酸提取率作为评价指标，优化了熊果酸的微波提取工艺。最优微波提取条件为：90 % 乙醇作为提取剂、料液比1∶20 g/mL、微波功率250 W、微波提取时间120 s。 |
| 英文摘要: |
| 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. |
