Zusammenfassung:	The invention discloses a preparation method and application of Juglans mandshurica polysaccharide, and the preparation method of the Juglans mandshurica polysaccharide comprises the following steps: extracting crude Juglans mandshurica polysaccharide by a water extraction and alcohol precipitation method, deproteinizing and purifying by a papain method, and freeze-drying the deproteinized polysaccharide solution to obtain the Juglans mandshurica polysaccharide. The obtained Juglans mandshurica polysaccharide has a remarkable effect on regulating intestinal flora, and further discloses that the Juglans mandshurica polysaccharide can reduce the relative abundance of harmful bacteria Alistipes bacteria and Lengmiaceae bacteria, can improve the relative abundance of beneficial bacteria Prevotellaceae, Blauria bacteria and the like, and can be used for improving the intestinal flora regulating effect of the Juglans mandshurica polysaccharide and improving the intestinal flora regulating effect of the Juglans mand
