The invention relates to a method for preparing bonito stick protein hydrolysate with an effect of reducing uric acid. The method comprises the following main steps of raw material heat treatment, restriction digestion, membrane separation-anion exchange chromatography-gel filtration chromatography separation, concentration and spray drying so as to obtain the bonito stick protein hydrolysate with an effect of reducing uric acid. The amino acid analysis indicates that the zymolyte peptide fragment primary amino acid sequence contains four amino acids, namely histidine, arginine, lysine and threonine, the total mass content of the four amino acids is 70 percent of the total amino acid content of zymolyte. MALDI-TOF-MS mass spectrum determines that the molecular weight of the main peptide effective ingredient is less than 700Da. In-vitro uric acid reduction experiments prove that the bonito stick protein hydrolysate has a remarkable effect of inhibiting generation of uric acid, and has an inhibition rate over 50 percent; an oteracil potassium molded hyperuricemic rat animal model indicates that the bonito stick protein hydrolysate can be used for remarkably reducing the level of serum uric acid and serum creatinine of rats, and shows a relatively good kidney protecting effect.

Provided is an enteric preparation for preventing and curing hyperuricemia and gout. The employing essential component of the preparation is enteric capsules of uricase. The causes of the hyperuricemia and the gout are that uric acid is over generated and / or the uric acid is diminished in discharging, and metabolic diseases increasing the density of serum uric acid. About one third of the uric acid of the human body is defecated from intestinal canals, and the uric acid entering the canals still can be reabsorbed. When the hyperuricemia and the gout happen, the proportion of the uric acid defecated from the intestinal canals is increased. The uricase is capable of rapidly effectively dissociating the uric acid. The uricase of the enteric preparation after being orally taken is disintegrated in the intestinal canals and is diffused from blood into the uric acid of the intestinal canals, preventing the uric acid from reabsorbing, thereby reducing the density of the serum uric acid, achieving the purposes of preventing and curing the hyperuricemia and the gout. The oral uricase has the characteristics of non-absorbent property by the intestinal canals, keeping out of blood circulation, no producing of antibodies of organisms and allergic response, providing a new method for preventing and curing the hyperuricemia and the gout.
