Problems solved by technology

However, if the amino acid is not "supplemented", qualified products cannot be produced, mainly because the fingerprint similarity cannot reach the 90% standard, and the injection products have floc and tyrosine precipitation during storage. Unqualified clarification due to substance etc.

Abstract

The invention discloses a pure natural cerebroprotein hydrolysate raw material preparation method. The method comprises the steps as follows: a, protein purification, to be specific, a cryopreserved fresh pig brain is defrosted, cleaned, homogenized, and subjected to centrifugal separation for obtaining precipitated brain protein; b, pepsin enzymolysis, to be specific, pepsin is added in the precipitated brain protein and stirred, then concentrated hydrochloric acid is added and stirred, and then the centrifugal separation carried out, so that a pepsin enzymatic hydrolysate is obtained; c, acid hydrolysis, to be specific, sulfuric acid is added into the pepsin enzymatic hydrolysate for hydrolyzing, so that an acid hydrolysis liquid is obtained; d, trypsin enzymolysis, to be specific, the pH value is adjusted to 7-9, and pancreatin with the weight 0.1% to 0.4% of that of the pig brain is added for hydrolyzing, and the centrifugal separation is carried out, so that a pancreatin enzymatic hydrolysate is obtained; e, chromatography, to be specific, the pH value is adjusted to 6.5-7.5, and resolving is carried out by using ammonia water, so that a chromatography liquid is obtained; f, concentration, to be specific, the vacuum concentration is carried out, the pH value is adjusted to 6.5-7.5, and then frozen storage is carried out; g, impurity removing, to be specific the condensed frozen liquid is defrosted, and then subjected to centrifugal separation as well as ultrafiltration for obtaining natural cerebroprotein hydrolysate raw material.

Description

technical field [0001] The invention relates to a raw material preparation method of pure natural cerebroprotein hydrolyzate. Background technique [0002] Pure natural cerebroprotein hydrolyzate is extracted from pig brain, without protein, and contains a variety of essential amino acids, non-essential amino acids, polypeptides, etc., and has broad medicinal prospects. In the 1970s, Cerebrolysin hydrolyzate was first sold by the Austrian EBEWE Pharmaceutical Factory under the trade name of Cerebrolysin (Shipushan), which was used for the treatment of various diseases such as infantile hypoplasia, senile dementia, sequelae of cerebrovascular disease and adjuvant treatment, and achieved good results. The effect has been affirmed by clinicians. However, the preparation method of the preparation was not disclosed in all literature data at that time. In 1995, the Ministry of Health approved the production of cerebroprotein hydrolyzate injection. However, the nitrogen content ...
