Moderate molecular weighted chondroitin sulfate injection and its preparing process

Abstract

The present invention discloses the injection of chondroitin sulfate in medium molecular weight and its preparation process. The injection of chondroitin sulfate includes chondroitin sulfate in medium molecular weight of 10,000-30,000 daltons and / or its salt and medicinal additive, and the medium molecular weight chondroitin sulfate is prepared through ultrafiltering and nanofiltering. Compared with common injection of chondroitin sulfate, the injection of the present invention has smaller molecular weight, higher pharmacological activity and higher purity, and can meet the requirement for safe administration.

Description

technical field

[0001] The invention relates to a medium molecular weight chondroitin sulfate injection and a preparation method thereof. Specifically, the invention relates to a medium molecular weight chondroitin sulfate injection with a molecular weight of 10,000-30,000 Daltons and a preparation method thereof. Background technique

[0002] Chondroitin Sulfate is a macromolecular acidic mucopolysaccharide prepared from the cartilage tissue of pigs, cattle, sheep and other animals and the cartilage of aquatic products such as sharks by using biochemical extraction technology. Chondroitin sulfate sodium salt, potassium salt, calcium salt, zinc salt, etc. are widely used in medicine, health products, food, cosmetics, pet feed, etc. For example, chondroitin sulfate can be used as a blood lipid-lowering drug for clinical treatment of hyperlipidemia. Chondroitin Sulfate A Sodium Injection has the effects of lowering blood lipids, resisting atherosclerotic plaque formation, anti...
