The invention provides modified spirulina polysaccharide with an effect of regulating intestinal steady state and application of the modified spirulina polysaccharide, and belongs to the technical field of biological medicines. The preparation method of the modified spirulina polysaccharide comprises the following steps: mixing spirulina polysaccharide with a hydrochloric acid solution to prepare a polysaccharide solution, then adding sodium selenite and vitamin C, carrying out microwave treatment, and carrying out alcohol precipitation, precipitate collection and drying to obtain the modified spirulina polysaccharide. The modified spirulina polysaccharide disclosed by the invention has a remarkable effect of regulating the steady state of the intestinal tract, and has an outstanding effect on intestinal tract ecological disorder induced by high-fat diet. The modified spirulina polysaccharide and the coptis chinensis extract are combined to prepare products for preventing and treating intestinal ecological imbalance caused by oral administration of antibiotics. The coptis chinensis extract prepared by the invention can inhibit gram-positive pathogenic bacteria and protect gram-negative beneficial bacteria, and cooperates with the modified spirulina polysaccharide to promote colonization of intestinal probiotics (bifidobacterium and lactobacillus) and improve intestinal ecological imbalance.
