Hawthorn Polysaccharides Relieve High-Fat Blood Disease in Mice by Improving Intestinal Flora and Promoting Lipid Metabolism

In this research, the anti-hyperlipidemic effects of hawthorn polysaccharides in experimental mice fed a high-fat diet were thoroughly investigated. The findings indicated that the body and organ weights of the high-fat group (HC) mice increased significantly, fat accumulation was evident, and serum indicators showed elevated lipid levels. After 8 weeks of the intragastric administration of hawthorn polysaccharides, the data showed that the body weight of the hawthorn polysaccharide (HA) group was notably lower than that of the HC group and close to that of the NC group. In addition, the hawthorn polysaccharide intervention improved the symptoms of the mice. In particular, the hawthorn polysaccharide intervention significantly increased HDL-C levels and decreased LDL-C levels in the HA group mice. Furthermore, gut microbiota analysis demonstrated that a high-fat diet altered its structure. The intervention with hawthorn polysaccharides modulated the intestinal flora structure, lowered the F/B ratio, and increased the abundance of beneficial bacterial strains associated with lower blood lipid levels.
