摘　　要：研究了超临界CO2萃取烟叶中茄尼醇的条件,发现萃取压力是主要影响因素,其次为夹带剂(75%乙醇)用量、萃取温度和CO2流量,其较佳萃取条件为:萃取压力20MPa,萃取温度40℃,75%乙醇用量1 5mL/g烟叶,CO2流量20kg/h,在此条件下茄尼醇的萃取率达79%以上。The conditions for solanesol extracting from tobacco with supercritical fluid CO2 were studied. It was found that the key factor influencing the yield of solanesol was extracting pressure. The optimum conditions for SCFE were as follows: pressure: 20MPa; temperature: 40℃; entrainer, 75% (v/v) alcohol: 1.5mL/g raw material; CO2 flowrate: 20kg/h. The yield of solanesol was over 79%.
