The invention discloses a radix astragali polysaccharide extraction and detection method; traditional Chinese medicine radix astragali is used as a raw material, extract yield, total sugar content and astragaloside are used as indexes, and an optimum radix astragali extraction method is determined by orthogonal experiment. The contents of the astragaloside and the radix astragali polysaccharide in radix astragali extract extracted by the method are detected, and the content of the astragaloside is 0.41%, the contents of the polysaccharide with monosaccharide oligosaccharide and the like be deducted is 42.4%. The contents of the main active ingredients of the astragaloside and the radix astragali polysaccharide in the radix astragali extract extracted by the method are higher, and the extraction method is simple, extraction yield is high, and the method has large market prospect. The invention also provides an effective radix astragali polysaccharide detection method capable of eliminating influence of glucose, sucrose and the like in the polysaccharides.
