Problems solved by technology

[0003] The existing rabbit muscle extract preparation method has the following defects. One is that the rabbit muscle needs to be repeatedly frozen and thawed to destroy the cell membrane and effectively extract the protein polypeptide product in the cell membrane. The freezing and thawing temperature and time of the rabbit muscle affect the polypeptide product. The second is to repeatedly thaw rabbit muscle at room temperature or higher than room temperature, which increases the risk of microbial infection of rabbit muscle and its extract and the freshness of rabbit muscle extract, which affects the quality and quality uniformity of the drug and quality control, efficacy and safety

Abstract

The invention aims to provide a preparation method of a cerebroside carnosine injection with good stability. The preparation method of a rabbit muscle extract for preparing the cerebroside carnosine injection comprises the following steps: mincing pretreated rabbit muscles into small blocks with the volume not higher than 1cm < 3 >; and uniformly mixing the obtained minced muscles with water for injection according to a ratio of 1: (1-3) (w / w), performing homogenizing, freezing the obtained muscle homogenate at a temperature not lower than-10 DEG C for 5-7 days, and performing melting at a temperature of 8-10 DEG C for 36-48 hours. According to the method, the extraction efficiency of the polypeptide in the rabbit muscle extract is remarkably improved, the risk that the rabbit muscle and the rabbit muscle extract are infected by microorganisms is effectively avoided, the freshness of the rabbit muscle extract is remarkably reduced, and the resource utilization rate of the rabbit muscle, the quality of drugs, the quality uniformity, the effectiveness and the safety are remarkably improved.

Description

technical field [0001] The invention relates to the field of medicine, and relates to a stable cerebroside and carnosine injection, a preparation method thereof and an application thereof. Background technique [0002] Cerebroside carnosine injection can penetrate the blood-brain barrier, and has the functions of repairing, regenerating, nourishing and protecting nerve tissue and peripheral nerves. It is clinically used in the treatment of stroke, senile dementia, neonatal hypoxic-ischemic encephalopathy, cerebral Brain injury, spinal cord injury, and central nervous system injury caused by other reasons, as well as peripheral nerve injury such as traumatic peripheral nerve injury, diabetic peripheral neuropathy, and compressive neuropathy. The active ingredients of cerebroside and carnosine injection are composed of rabbit muscle extract and bovine brain ganglioside extract. The main active ingredients include polypeptides, various gangliosides, free amino acids, nucleic ac...
