The effects of every main factors on extraction ratio are discussed, and the optimum conditions of extraction effective components from zizyphus jujuba are determined with the orthogonal test. Optimum conditions are obtained by using a new method of H2O2-decoloring in alkalescent condition, and effects of correlation factors on decoloring ratio are discussed. The yield ratio of polysaccharide is above 5.26% under these optimum conditions.
