Cynomorium in recent years on the study mainly concentrated in pharmacology, physical and chemical nature of the analysis, but the extraction process on very few reports. Through a single factor orthogonal test pilot and a Cynomorium polysaccharide determine the best extraction process showed that the ratio of 15:1 in the material, the extraction time is 2 h, from the temperature at 90 ℃ polysaccharide content of the highest Cynomorium . At the same time, Cynomorium polysaccharide extract protein from the methods of the study to removal of protein and polysaccharide loss rate for the Evaluation of several common methods of removing protein were compared to determine the Cynomorium polysaccharide The best method for removing protein enzyme and Sevag with law, so as to the active ingredient Cynomorium provide the basis for the development of information.
