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%.

Abstract

The invention discloses a method for extracting enzymes in animal placenta, which comprises the following steps: 1) using animal placenta as a raw material, undergoing pretreatment, crushing, ultrasonic wall breaking twice, adding water and homogenizing to obtain a mixed solution; 2) the The mixed solution obtained in step 1) is centrifuged to obtain a cell stock solution; 3) the cell stock solution obtained in step 2) is adsorbed by an ion exchange resin, eluted, filtered and dialyzed, and freeze-dried to obtain an enzyme product; the enzyme The product yield is high and the stability is good, and the enzyme content in the enzyme product is high.

Description

technical field [0001] The invention relates to the fields of medicine and health products, in particular to a method for extracting enzymes in animal placenta. Background technique [0002] Animal placenta, also known as afterbirth, is a transitional organ for exchanging substances between mother and child formed by embryonic membrane and maternal endometrium during pregnancy in mammals. Animal placenta contains a variety of enzymes with application value. However, most of the methods commonly used in the market for extracting active ingredients in animal placenta are animal element extracts, and the extraction method is not suitable for extracting enzymes in animal placenta. Contents of the invention [0003] In view of this, the present application provides a method for extracting enzymes in animal placenta, the enzyme product has high yield and good stability, and the enzyme product has high enzyme content. [0004] In order to solve the above technical problems, the ...
