This paper studied technology of extracting polysaccharide from jujube juice which has been extracted c-AMP. The extracting liquid contract 4 times, adding ethanol to make the concentration of alcohol 60%, and time was 5 h. Papain was used to remove protein, and the optimum conditions including 0.4∶ 1V/V papain, temperature 60℃, pH5.0, 90 min. This method may increase the removal rate of protein to 91.8%, and the loss rate of polysaccharides in reduced greatly. The extracted solution was then decolorized through macro-reticular adsorption resin column. The rate was 73.64% and the yield of polysaccharide was 94.4%. The structure was similar to the polysaccharide extracted by normal technology.
