Abstract: The optimal process of extracting polysaccharides from Flammuling velutipes(Cart.) Sing was studied by single factor test and orthogonal test. The results showed that the optimum conditions for extracting the polysaccharides assisted by ultrasonic wave are as follow:material-liquid ratio 1:100,ultrasonic power 80 W,pH 8.0 and extraction time 10 minutes. The ultrasonic extraction method is better than the hot water extraction method,owing to higher extraction rate.

Key words: Flammuling velutipes(Cart.) Sing, polysaccharides, ultrasonic wave, extraction
