Abstract: In order to explore the feasibility of microwave-assisted procedure for  extraction polysaccharide from Evodia rutaecarpa, on the basis of single factor experiments with three factors and three levels of response surface analysis, this paper won the second equation of linear regression (P<0.01) using the software Box-Behnken experiment design principle. The response surface figure were built with polysaccharide extraction yield as response values to determine the optimum parameters of microwave extraction of Evodia rutaecarpa polysaccharide as follows: microwave power of 400 W, extraction time of 100 s, extraction times of 2, and solid-liquid ratio of 1∶100; Evodia rutaecarpa polysaccharide extraction rate was 21.7%（predictive value of 21.9%, the traditional water extraction was only 12.3%）, validation experiments showed  that the model equation can well predict the result of the experiment, the fitting was good.

Key words: microwave-assisted extraction, response surface methodology, Evodia rutaecarpa polysaccharide
