| Abstract: | The extraction rate was used as index to evaluate the results of ultrasonic extraction of polysaccharide from Cynomorium songaricum in orthogonal experiment,in which 4 factors considered were extraction time(A),extraction temperature(B),the solvent volume(C) and the ultrasonic power(D).The results indicated that the optimal conditions of ultrasonic extraction were as liquid∶material 12∶1,ultrasonic power 200 W;extracting 30 minutes at 90 ℃.The extraction rate of polysaccharide reached 25.41 mg/g under these conditions. |
