[Objective]The present experiment was conducted to optimize extraction technology of polyphenol from oil-tea （Camellia oleifera L.） seed cake using ethanol through ultrasonic method. [Method]Single factor experiment and orthogonal experiment were performed to observe ultrasound intensity, extracting time, extracting temperature,ethanol concentration and material/liquid ratio. [Result]Considering production cost and extraction efficiency, the optimum parameters identified were as follows： ultrasonic intensity of 300 W, extracting time of 0.5 h,extracting temperature of 60℃,ethanol concentration of 40% and material/liquid ratio of 1：15. ] Conclusion ]Under the best processing techniqicale circumstances, the extraction ratio of polyphenol was highest which indicated that ultrasonic method can greatly boost up the extraction efficiency.
