He invention discloses a nauclea officinalis oral liquid which comprises the material components of a nauclea officinalis extractum concentrated solution, saccharose, poria cocos and astragalus membranaceus by weight ratio. The nauclea officinalisoral liquid does not contain other additives or preservatives except saccharose, the cold property of the nauclea officinalis extractum concentrated solution is balanced by adding reasonable dosage of the poria cocos and the astragalus membranaceus, the spleen and the stomach of a patient are further protected, the diarrhea phenomenon caused by coldness of the commonly seen heat-clearing and detoxicating drug is avoided, and in addition, the heat-clearing and detoxicating effects of the nauclea officinalis oral liquid added with the poria cocos and the astragalus membranaceus are better than those of the nauclea officinalis oral liquid with no poria cocos or astragalus membranaceus under the condition that the dosages of the nauclea officinalis extractum concentrated solution and the saccharose are the same.

The invention discloses a fermentation and enzymolysis preparation method of leaf-shaped fish small peptides, which comprises the following steps: crushing leaf-shaped fish, degreasing and hydrolyzing to obtain a hydrolysate; carrying out enzymolysis on the hydrolysate by using a compound enzyme to obtain an enzymatic hydrolysate; fermenting the enzymatic hydrolysate with microorganisms to obtain fermentation liquor; filtering the fermentation liquid, and collecting supernatant to obtain a crude peptide liquid; then repeating the processes of enzymolysis, fermentation and filtration on the remaining impurities to obtain a crude peptide liquid again; purifying the crude peptide liquids obtained twice by using a G-15 sephadex column, separating by using gel chromatography to obtain a small peptide liquid containing aspartic acid-arginine-histidine-lysine as an amino acid fragment, and drying and dehumidifying the small peptide liquid to obtain the small peptides of leaf-shaped fish. According to the method provided by the invention, the problems that the small peptide is bitter and easy to damp are solved, and meanwhile, the obtained small peptide is used in nursery pig feed, so that the intestinal development and growth performance of nursery pigs is improved, heat stress in summer and cold stress in winter are relieved, the breeding benefit is improved, and a high-quality protein source is provided for pig raising production.
