Embodiment 1
[0041] A method for extracting enzymes in animal placenta, comprising the steps of:
[0042] 1) Using animal placenta as raw material, after cleaning, removing impurities, and cutting into 0.5-1.5cm 3 fragments, pulverized, ultrasonically broken twice, and homogenized with water to obtain a mixed solution;
[0043] 2) The mixed solution obtained in the step 1) is centrifuged to obtain the cell stock solution;
[0044] 3) The cell stock solution obtained in step 2) is adjusted to a pH value of 4-6.5, and after being adsorbed by a weakly acidic cation exchange resin, it is eluted with ammonium sulfate at a flow rate of 2-4 mL / min, and the molecular cut-off flow rate is 3000 The ~10000Da dialysis membrane is subjected to filtration and dialysis treatment, freeze-dried to obtain an enzyme product; the enzyme product includes: alkaline phosphatase, lactate dehydrogenase and superoxide dismutase.
[0045] Wherein, the conditions for the two times of ultrasonic wall breaking are: u...
Embodiment 2
[0048] The difference between this embodiment and Embodiment 1 is that the ultrasonic wall breaking conditions of the two times are: the ultrasonic power is 200w, the frequency is 25Hz, and the ultrasonic time is 15-20min.
[0049] The yield of the enzyme product in this embodiment is 3.10%, and the enzyme content in the enzyme product is 66%.
Embodiment 3
[0051] The difference between this embodiment and Embodiment 1 is that the ultrasonic wall breaking conditions of the two times are: ultrasonic power is 350w, frequency is 45Hz, and ultrasonic time is 15-20min.
[0052] The yield of the enzyme product in this embodiment is 3.25%, and the enzyme content in the enzyme product is 64%.
