Abstract: Based on orthogonal design, by testing the parameters of liquid-solid ratio, concentration of alcohol and duration of microwave process, the conditions of the technique of microwave extraction of total flavones content from Glycyrrhiza Uralensis were optimized by referring the results of spectrophotometrie measurement of the total flavones as the overall evaluation indexes. The study showed that the optimum conditions for microwave extraction of total flavones from licorice are: 1:8 liquid-solid ratio, 85 % alcohol concentration, and 3 min low fire microwave process.
