%X Based on the preliminary experiments, a three-variable, three-level Box-Behnken design was performed to study microwave-assisted extraction of genistein from the roots of pigeon pea. The optimum parameters were as follows: extraction temperature 68 ℃, liquid/solid ratio 32∶1 mL&middot;g<sup>-1</sup>, ethanol concentration 78%, extraction power 700 W and extraction time 15 min. Under the optimal conditions, the average extraction yield of genistein was 0.465&plusmn;0.032 mg&middot;g<sup>-1</sup>. This study is significant for the application of microwave extraction technology and utilization of the pigeon pea root.
