Abstract

To study the best extraction condition of microwave extraction of flavones in Sophora flavescens.The influencing rules of the flavones in Sophora flavescens were studied basing on the yield of extracts.Orthogonal experiment was carried out to investigate 4 influential factors of alcohol concentration,microwave extracting time,microwave power and ratio of solid to liquid.Results:The best extraction condition of flavones in Sophora flavescens were determined,which showed that alcohol concentration was 10 %,microwave extracting time was 6 min,microwave power was 420 W,ratio of solid to liquid was 1∶25(g/mL).In this extraction condition,the yield of extracts of flavones in Sophora flavescens was 23.11 %.Conclusion:It shows a promising prospect for extracting flavones in Sophora flavescens by using microwave extraction.
