채용미파제취법,선취이상제취용제、미파시간、온도、공솔、료액비、을순농도작위제취인소,진행단인소실험,선취기중영향교대자진행L9(34)정교시험,래우화하고초중제돈과산적제취공예.결과표명,하고초중제돈과산적최가제취조건위이90%을순용액위용제,온도70℃,미파시간120 s,료액비1∶20(g∶mL),제취솔최고가고체13.87%.
@@@@the microwave extraction, microwave extraction solvent, select the ideal time, temperature, power, material to liquid ratio, ethanol concentration as extraction factors, the single factor experiment, the effect of selected shorter lengths to L9(34)orthogonal test, to optimize selfheal oleanolic acid in the extraction process.The results show that selfheal oleanolic acid in the best extraction conditions for 90%ethanol as solvent solution to 70℃, the temperature, time 120 s, microwave material liquid, the highest rate than what can be as high as 13.87%.
