Abstract: The effects of grinding degree of dried ginger,extraction pressure,extraction temperature,extraction time and flow rate of CO2 on extraction rate of ginger essential oi by supercritical CO2 method were explored,and the main parameters were optimized by orthogonal test. The results showed that under the condions of extraction pressure 30Mpa,extraction temperature 45℃,extraction time 2.5h and flow rate CO2 380 kg/h,the extraction rate of the ginger essential oil reaches 1.81%.
