摘　　要：采用CO2超临界流体萃取技术从山奈中分离出山奈油树脂,研究了在超临界状态下,萃取压力、CO2泵频率、萃取温度、萃取时间等因素对山奈油树脂萃取率的影响,确定最佳工艺参数为:萃取压力20MPa,CO2频率10赫兹,萃取温度50,时间1.5小时,萃取率10.71%。Supercritical fluid extraction is a late model technology of extraction. Kaempferia galamga was taken as experimental material of extraction. This paper studied the influence of extraction condition on the extraction rate by supercritical,the parameter of technology were defined:pressure of 20MPa,frequency 10Hz,temperate50,time of 1.5h,the extraction rate 10.71%.
