ABSTRACT Objective: To optimum the extraction procedure for polysaccharide from radix astragali by water extraction. Method: Orthogonal test was used,optimum the extraction of procedure polysaccharide was selected Phenolsulfuric as the the content index.Result: The optimum extraction procedure was as fallow: 12 times of water decocting 0.5 h and 2 times, and the polysaccharide yield was 2.7%.Conclusion: The optimum extraction procedure was simple and quick.
KEY WORDS Radix astragali; Astragaluspolysaccharose; Water extraction; Orthogonal test
