HU Jian-feng1,2,QIU Shu-yi1,2*(1.College of Chemistry and Chemical Industry,Guizhou University,Guiyang,Guizhou 550003;2.Guizhou Key Laboratory of Fermentation Engineering and Bio-pharmacy,Guiyang,Guizhou 550003,China)  
Three extraction methods including conventional water extraction,ultrasonic recycle extraction and microwave extraction method were tested to extract inulin from Jerusalem artichoke.The results showed that the optimum condition of the conventional water extraction method was 60℃,40 min and 1∶30 raw material/solution ratio,the optimum condition of the ultrasonic recycle extraction method was 600 W and 1∶ 20 raw material/solution ratio and the optimum condition of the microwave extraction method was 700 W,8 min and 1∶15 raw material/solution ratio.The inulin extraction rate of the conventional water extraction method,ultrasonic recycle extraction method and microwave extraction method was 75.68%,82.16% and 87.81% respectively and the inulin extraction rate of the microwave extraction method was the highest among three extraction methods.
