Lonicerae flos polysaccharide for improving non-alcoholic fatty liver disease as well as preparation method and application of lonicerae flos polysaccharide

The invention belongs to the technical field of biology, and particularly provides flos lonicerae polysaccharide for improving non-alcoholic fatty liver disease, which comprises arabinose, rhamnose, ribose, xylose, mannose, fructose, galactose and glucose. The invention also provides a preparation method of the lonicerae flos polysaccharide, and the lonicerae flos polysaccharide prepared by the method is high in purity, clear in active ingredient structural characteristics and controllable in quality. The lonicerae flos polysaccharide not only can relieve abnormal glucose metabolism and insulin resistance in non-alcoholic fatty liver disease (NAFLD), but also can relieve the progress of metabolic stress-induced non-alcoholic steatohepatitis (NASH) by reducing lipid accumulation and inhibiting expression of genes and proteins related to lipid synthesis. In addition, by improving the intestinal flora structure, the traditional Chinese medicine composition has a good protection effect on liver fatty degeneration
