摘　　要：通过单因素及正交试验确定了超临界CO_(2)逆流萃取鲜花椒树脂挥发油的可行性,并得到了最佳萃取条件及分离条件,其最适萃取条件为萃取时间7 h、萃取温度45℃、CO_(2)流量600 L/h、萃取压力20 MPa。萃取后的挥发油最适分离条件为分离器Ⅰ压力11 MPa、温度40℃,分离器Ⅱ压力5~6 MPa(由气源决定不可调)、温度55℃,可高效地从鲜花椒树脂中分离出2种香气不同的挥发油。Through single factor and orthogonal experiments,the feasibility of supercritical CO_(2) countercurrent extraction of volatile oil from fresh Zanthoxylum bungeanum oleoresin was determined,and the optimal extraction conditions and separation conditions were obtained.The optimal extraction conditions were extraction time 7 h,extraction temperature 45℃,CO_(2) flow rate 600 L/h and extraction pressure20 MPa.The optimum separation conditions for the extracted volatile oil were as follows:separator I pressure 11 MPa,temperature 40℃,separator II pressure 5~6 MPa(not adjustable depending on gas source),temperature 55℃.Two kinds of volatile oils with different aroma can be efficiently separated from fresh Zanthoxylum bungeanum oleoresin.
