| Abstract: | Box-Behnken center-united experiment design attached to response surface method was applied to optimize the extraction condition for Astragalus polysaccharides(APS)by cellulase.How the parameters which influence the content of APS,such as pH value,reaction temperature and enzymatic quantity were dis- cussed.The results indicated that the optimal parameters of extraction technology for the content of APS by cellulase were:pH value 4.0,reaction temperature 56.5℃,enzymatic quantity 61U/g.The maximal content of APS in average was 20.31% in this paper. |
