| Abstract: | A microwave-assisted extraction （MAE） method was studied for the extraction of DNJ from mulberry leaves. Microwave-assisted extraction for DNJ from mulberry leaves was done by using water as the solvent, and experimental factors, such as microwave power, irradiation time, ratio of solid to solvent （g / mL） and extraction time were investigated .Optimizing tests showed that microwave power was 406 W, microwave irradiation time was 1.Smin, solid to water ratio wasl ： 40, and the extraction stages were 2. The MAE method is fast, efficient, energy-saving and highly-selective for extraction DNJ from mulberry leaves. |
