In recent research , people paid main attention to the resource investigation, biology, chemistry and pharmacology, and so on. But research on extraction technology have few report. This experiments based on the extraction rate of Cynomorium polysaccharide was optimized single factor and orthogonal design. The result showed that the optimum conditions for the extraction process as follows：the ratio of material to solution is 1：20 and the extraction at 80℃ for 1h．Meanwhile ,the methods of deproteinization from Cynomorium songaricum Rupr polysaccharide had been researched. We compared the several deproteinization method by the evaluation of their polysaccharide loss rate and deproteinization rate and eventually we identified the best method for deproteinization was enzyme and Sevag method. The basical research are hoped to provide a theoretical foundation for the active ingredient and effectiveness of development and intensive processing. Key words：Cynomorium songaricum Rupr；extraction process of polysaccharides；deproteinization 目 录
