The invention discloses an oligopeptide, a preparation method and application thereof, wherein the amino acid sequence of the oligopeptide is Phe-Pro-Gln-Tyr-Leu-Gln-Tyr-Pro-Tyr, and the oligopeptide converts angiotensin into The IC50 of the enzyme was 24.447 μg/mL. The invention obtains an oligopeptide with an inhibitory effect on angiotensin converting enzyme after hydrolyzing, separating and purifying goat milk casein, which is expected to be applied to the field of lowering blood pressure and lays a foundation for the application of the natural product antihypertensive peptide in the future. |
