| Abstract: | Objective ：To confirm the optimum technological conditions of Astragalus polysaccharides （APS） composition of ultrasonic extraction auxiliary. Method： APS content was determined by using phenol hydrate sulfuric method, the regression model was gotten by using the response surface method on the main process parameters optimization, which ensured the extraction technology. Result：The optimum process conditions, ultrasonic power 600W, extracting time 46 min and liquid materials than 35：1 plead, the rate of APS 3. 134%, The relative error was non -attendance 1% between the regression model and the reality measured value, the fitting between the regression equation and the actual situation was good. Conclusion：The method is relatively economic and scientific. |
