| Abstract: | In this paper,the microwave-assisted extraction conditions of flavones from Potentilla freyniana were studied.The effects of the ethanol concentration,the microwave power,the extraction time,the refluxing temperature,and the ratio of material to liquid on microwave extraction of Potentilla freyniana were investigated with single factor experiment.The optimum extraction conditions were: 75 % ethanol,material-liquid ratio 1∶25(g/mL),70 ℃ extracted for 5 min with microwave power 400 W.The total content of flavones was 4.24 %. |
