The invention discloses a can increase the immune function of Desmodium polysaccharide, solves the increase of adverse drug reactions of human immunity effect is not obvious, the exact problem. The present invention Jinqiancao polysaccharide is composed of Desmodium degreasing, water extraction and alcohol precipitation, and then dialysis intercept molecular weight of more than 10000 Dalton components by macroporous weakly basic anion exchange resin separation system. The preparation method of the invention comprises the following steps: degreasing, water extraction, alcohol precipitation and dialysis, and drying on the macroporous weak basic anion exchange resin column chromatography. The present invention Jinqiancao polysaccharide in preparation can increase the immune function of food, food or drug use in health care. The method has the advantages of accurate effect, small adverse reaction, simple preparation method and simple operation, and is suitable for industrial production.
