The invention relates to an enteric material coated chitosan nanoparticle which covers insulin and cell-penetrating peptide Tat and a preparation method of the chitosan nanoparticle. The chitosan nanoparticle is prepared from an enteric material, namely Eudragit S100, insulin, cell-penetrating peptide and chitosan. With the oral administration of the prepared enteric coated insulin chitosan nanoparticle, the amount of loaded contents released from the chitosan nanoparticle in the stomach and the upper part of the small intestine can be greatly reduced due to the protective effect of the enteric material, namely Eudragit S100. As the chitosan nanoparticle arrives at the lower end of the digestive tract, the enteric coating material on the surface of the chitosan nanoparticle begins to dissolve and the chitosan nanoparticle becomes exposed with the increase of pH value; the chitosan nanoparticle is damaged under a weakly alkaline condition, so that the cell-penetrating peptide and the insulin therein are released. The cell-penetrating peptide is capable of prompting the absorption of colonic epithelial cells to the insulin so as to improve the bioavailability of the insulin through oral administration.
