Abstract: In this research, the optimum extracting conditions of Nitraria polysaccharide were investigated by orthogonal test. Lipid and monosaccharide were removed before the extraction of polysaccharide. The results showed that under the conditions 94 ℃, 1:5(W/V), extracting 3 times and 2 h for each time, the content of polysaccharide is 34.562 mg/g.

Key words: Nitraria tangutorun Bobr., polysaccharide, extraction process
