The invention discloses anti-inflammatory polypeptide nanoparticles and a preparation method thereof, and belongs to the technical field of bioactive peptides. The anti-inflammatory polypeptide nano-particles are nano-particles obtained by coating polypeptide with an anti-inflammatory effect with chitosan and sodium tripolyphosphate, the polypeptide with the anti-inflammatory effect contains bioactive peptides of which the amino acid sequences are YAADQ, FPYTT and YVTYA. The phycocyanin anti-inflammatory peptide is natural in source, the performance of the phycocyanin anti-inflammatory peptide can be remarkably improved through the nanometer embedding technology, and compared with traditional drugs, the phycocyanin anti-inflammatory peptide has lower toxic and side effects and potential cost advantages. The polypeptide nanoparticles prepared by the invention can effectively prevent the phycocyanin anti-inflammatory peptide from being degraded in the digestive tract, have a remarkable treatment effect on mice with ulcerative colitis, and have an important application prospect in preparation of ulcerative colitis prevention and treatment products.
