| titleOfInvention | A kind of preparation method of donkey placenta active polypeptide |
| abstract | The embodiment of the present invention discloses a preparation method of donkey placenta active polypeptide, comprising the following steps: Step 100, after selecting fresh donkey placenta tissue for washing and shredding, placing it in a buffer to perform homogenization and centrifugation to obtain the above supernatant; step 200, adding protease to the supernatant to carry out enzymolysis reaction to obtain an enzymolysis solution; step 300, heating the enzymolysis solution to carry out an enzyme inactivation treatment process to obtain a donkey placenta active polypeptide solution; step 400, removing the donkey placenta The active polypeptide liquid is freeze-dried to obtain donkey placenta active polypeptide dry powder. The invention mainly adopts the biological buffer of salt ions and organic solvent to perform tissue homogenization to obtain the supernatant, which can effectively change the solubility of the protein, so that the protein that is not easily soluble in the water phase is dissolved, and the extraction abundance of placental protein is improved. Extraction rate; compared with the traditional process, the donkey placenta active polypeptide obtained has a higher degree of hydrolysis and a smaller molecular weight, which is easy to achieve large-scale production. |
