Abstract:

This paper describes the optimization of extraction process of polysaccharides from Sophora alopecuraides L. seeds by response surface analysis (RSA), where the effects of extraction temperature, length of extraction time and material-to-water ratio and their interactions on polysaccharide yield were dealt with. The optimal conditions for the extraction of polysaccharides from Sophora alopecuraides L. seeds were obtained to be: e the optimization of extraction process temperature 75 ℃, length of extraction time 3 h and material-to-water ratio 1: 25, and the maximum polysaccharide yield was 70.25% under these conditions.

Key words: response surface analysis, Sophora alopecuraides L. seeds, polysaccharides, extraction
