Preparation method and application of nitraria sibirica pall polysaccharide effective part

The invention relates to a preparation method and application of a nitraria sibirica pall polysaccharide effective part, and the method comprises the following steps of: drying nitraria sibirica pallfruits, performing pulverizing, conducting degreasing with petroleum ether, carrying out decolorizing with chloroform-methanol, and performing refluxing with ethanol, then conducting extraction by a hot water extraction method, an ultrasonic-assisted extraction method, a cellulase extraction method, a pectinase extraction method, a pectinase+ultrasonic-assisted extraction method and the like, centrifuging an extracted solution, performing purifying by using macroporous adsorption resin, conducting concentrating, performing precipitating by using anhydrous ethanol, conducting centrifuging, andcarrying out vacuum freeze drying on a polysaccharide precipitate to prepare the nitraria sibirica pall polysaccharide effective part. The nitraria sibirica pall polysaccharide effective part obtainedby the method is verified
