The invention provides a bovine
colostrum powder, a preparation method and a preparation thereof, and an application thereof in the preparation of a tumor treatment
drug, and relates to the field of antitumor drugs. The bovine
colostrum powder contains immunoglobulin,
lactoferrin,
proline-rich polypeptides and various other bioactive components, fully utilizes the synergistic effects among the bioactive components of bovine
colostrum, and has high nutritional values and medicinal values. The bovine colostrum
powder is obtained by sequentially removing fats, macromolecular proteins, small molecular impurities and water from the bovine colostrum, so the original characteristics of all the bioactive components are retained, the bovine colostrums is maximally used, and the
utilization rate ofthe bovine colostrums is improved. The preparation prepared from the bovine colostrum powder has the advantages of low cost, convenience in taking, safety and no toxic or side effects, contains various bioactive components, can regulate the immune balance of the
human body and improve the
cell activity, can be used for treating tumors, and can be applied to the production of the tumor treatment drugs.
