@@@@To optimize conditions for extracting red pigment from the leaf of Berberis thunbergii var atropurpurea. Based on the single factor and orthogonal test, three factors and three levels by Box-Behnken design, response surface method was applied to optimize the extraction process. It showed that the microwave power, microwave irradiation time and the ratio of solid to solution were importent to the extraction yield of Berberis thunbergii leaf red pigments (BTRP).Experimental data were analyzed by solving the regression equation with Design Expert 8.0.6.1.It was indicated that the model was significant(p<0.000 1), R2=0.981 0 and the optimum extraction parameters were microwave energy 22.1 kJ,the ratio of solid to solution 1∶30.27 (g∶mL) and ethanol content 92%.Under these conditions, the red pigments extraction yield was highest. It had maximal extraction yield of BTRP with optimized technique parameters.
