Embodiment 1

[0095] Embodiment 1, preparation and detection of velvet antler protein extract

[0096] 1. Preparation of deer antler protein extract

[0097] Prepare deer antler protein extract according to the following method:

[0098] The fresh velvet antler is directly crushed for the first time with a pulverizer to obtain the first crushed velvet antler. Put the velvet antler crushed for the first time into liquid nitrogen quick-freezing, put it into a superfine pulverizer, add an appropriate amount of water for the second crushing until it is minced meat, and obtain the second crushed velvet antler, the molecular particle size of the second crushed velvet antler is 75 μm. Add a certain amount of water to the second crushed velvet antler (the mass ratio of the second crushed velvet to water is 1:5), then add an appropriate amount of glacial acetic acid to keep the pH at 3.5, keep it at 4°C for 24 hours, and then centrifuge at 4000g for 10 minutes to separate The supernatant is clear...

Abstract

The invention provides velvet antler protein extract. The velvet antler protein extract is characterized by being obtained through the following method which comprises the steps that 1, velvet antler is smashed to obtain a velvet antler smashed material, water extraction is conducted on the velvet antler smashed material, water-soluble matter is collected, and velvet antler water-soluble extract is obtained; 2, the velvet antler water-soluble extract is dialyzed through water till the pH value ranges from 6.5 to 8.5, dialysis is completed, and the velvet antler protein extract is obtained. The velvet antler protein extract can be used for preventing and curing myocardial infarction.

Description

[0001] This application claims the priority of the Chinese invention patent application No. 201510408556.9 entitled "Preparation method of deer antler extract and related products" filed by the same applicant on July 13, 2015. technical field [0002] The application relates to an extract of Chinese medicinal materials and its pharmaceutical use, specifically an antler protein extract and its pharmaceutical use. Background technique [0003] Deer antler is the unossified and densely hairy young horn of the sika deer or red deer, an animal of the chordate phylum Mammalia deer family. Antler was first recorded in "Shen Nong's Materia Medica", listed as a Chinese medicine, and is one of the traditional Chinese medicines in my country. Warm in nature, sweet in taste, salty in liver and kidney channels. Functions and indications: strengthen Yuanyang, invigorate qi and blood, benefit essence, strengthen muscles and bones. [0004] Antler is the only appendage in mammals with ful...
