wonder! Comprehensive disassembly of the extraction technology details of heparin sodium

Release time:


Since 2009, the export volume of heparin sodium products in China has been continuously soaring, and many manufacturers have invested in the production of heparin sodium to seize this opportunity. However, due to differences in production processes and extraction techniques, the quality of its products has also been severely unstable. Therefore, we will introduce in detail the extraction and production processes of heparin sodium.

1Heparin raw material processing

The product of heparin sodium is based on the substance "heparin", which happens to be present in pig intestines, so it must be extracted from fresh pig intestines. Firstly, carefully wash off the dirt and fat with clean water, then grind it into small pieces and stir thoroughly before adding an appropriate amount of water to mix. Some manufacturers may add a small amount of 0.1% solubility preservative and mix evenly.

2Heparin enzymatic hydrolysis extraction

1. After the raw materials are stirred evenly, use a small amount of dilute alkaline solution to adjust the pH value, and then add the freshly crushed pancreatic juice as an enzymatic hydrolysis agent. After stirring evenly, slowly raise the temperature and observe the pH change. It is advisable to maintain the pH value between 8.0 and 8.5.

2. After reaching the pH value, add a small amount of pig pancreatic juice and continue enzymatic hydrolysis for about 4 hours. If the pH of the enzymatic hydrolysis material decreases during the hydrolysis process, it is necessary to adjust it in a timely manner with 5% -8% sodium hydroxide solution. After adjusting with hydrochloric acid, the pH value is between 5.5-6, and then continue to heat up.

3. After stirring thoroughly and evenly, add sodium chloride, calcium, magnesium, etc. to mix them together, and then heat them up. After that, filter and remove impurities before fully cooling. Once the filtrate has cooled to around 35 degrees, adjust the pH value again with dilute alkaline solution, and then filter finely.

3Ion exchange adsorption

1. After enzymatic hydrolysis and extraction, remove the oil layer floating on the surface of the liquid, and then heat it up. After the temperature reaches the required level, stop heating.

2. Under continuous stirring, add the treated resin to effectively adsorb the heparin sodium component in the feed solution. After treatment for 3 hours, let it stand and filter.

3. Combine and filter the liquid and semen, then adjust the pH value, add ethanol to precipitate for one night, then dry and suck out the upper clear liquid, collect the lower sediment, filter it until dry, and then vacuum dry it to obtain crude heparin sodium.

4Preparation of high-quality heparin sodium

1. Dissolve the obtained crude product in a NaCl solution, and during this period, appropriately raise the temperature to assist in dissolution. Then, finely adjust the obtained material using a sodium hydroxide solution.

2. After the temperature of the material solution in the first step has cooled down sufficiently, it can be finely filtered once, and then re filtered again. A small amount of sodium hydroxide solution can be used to adjust the pH.

3. Using ethanol for precipitation, collect the precipitate. After dehydration with ethanol, the precipitate is refined and then dehydrated with acetone, ground and dehydrated, and dried under vacuum conditions of 50-60 degrees Celsius to obtain high-quality heparin sodium.

The above is the extraction and production process of heparin sodium products, paying attention to the specific requirements during the production process. As one of the main suppliers of heparin products, Desheng has a simple production process and stable product performance, which can effectively meet customer needs.
