The production of naringin of Guanxi honey pomelo , used carbon dioxide as a medium by supercritical fluid extraction technology to pomelo peel essential oil from pomelo skin , response surface methodology(RSM) was employed to optimize the extraction. According to the principle of Box-Behnken central composite design, extraction pressure, extraction temperature, extraction time and carbon dioxide flow rate were chosen as response factors, extraction mass as response value, and a four-factor and three levels central composite design was adopted to determine the influence of various technological conditions. The results showed that better extraction conditions were 59.97℃of temperature, 25 MPa of extracting pressure,150min of period, 15 L/h of CO2 flow rate. Under these conditions, the yield of pomelo skin oil was 5.62%.
