Oleanolic acid is prepared by microwave assist method from Papaya powder in this paper. The single factor experiment is carried out including microwave power,solid-liquid ratio,ethanol concentration,extracting temperature,and extracting time. At the same time,the optimum condition of extraction is determined through orthogonal experiment design. The result shows that the optimum conditions are as follows:microwave power 200 W,ratio of solid-liquid is 1∶8,ethanol concentration is 70%,extracting temperature is 65 ℃,extracting time is 30 min. Under these conditions,the yield of oleanolic acid is 2.712%.
