Chondroitin sulfate powder introduction

Chondroitinsulfate (CS) is an acidic mucopolysaccharide extracted and purified from animal cartilage tissue. Chondroitin sulfate has different structures such as A, C, D, E, H and K. Chondroitin sulfate in nature is mostly found in animal cartilage, throat bone, nasal bone (41% in pigs), bovine, horse septum and trachea (containing 36% to 39%), other tissues such as leg bones, ligaments, skin, cornea, etc. are also contained. The content of fish cartilage is very rich, such as 50% to 60% in shark bone, and very little in connective tissue.

Chondroitin sulfate powder clinical application

1. Chondroitin sulfate, as a health food or health medicine, it has been used for a long time to prevent and treat coronary heart disease, angina pectoris, myocardial infarction, coronary atherosclerosis, myocardial ischemia and other diseases, without obvious side effects, and it can significantly reduce the morbidity and mortality of patients with coronary heart disease. Long term clinical application has found that fat and other lipids deposited on arterial and venous walls can be effectively removed or reduced, which can significantly reduce plasma cholesterol, thus preventing the formation of atherosclerosis.

2. Chondroitin sulfate is used for the treatment of neuralgia, neuropathic migraine, arthralgia, arthritis and scapular joint pain, pain after abdominal surgery, etc.

3. It is effective in preventing and treating hearing impairment caused by streptomycin, hearing difficulties and tinnitus caused by various noises.

4. Adjuvant therapy for chronic nephritis, chronic hepatitis, keratitis and corneal ulcer.

5. In recent years, it has been reported that chondroitin in shark cartilage has an anti-tumor effect. In addition, chondroitin sulfate is also used in cosmetics and wound healing agents.

6. Chondroitin sulfate is also used in eye drops.

Chondroitin sulfate powder production method

The pig throat and nasal cartilage were extracted with 2% sodium hydroxide, and the extract was hydrolyzed with crude trypsin at 50°C to remove impurities such as protein. After filtering, the pH of the enzymatic hydrolysis solution was adjusted to 6, and ethanol was added to make the ethanol concentration reach 75%. Centrifuge to obtain a precipitate, namely the crude chondroitin sulfate product. The finished product is obtained through multi-step refining. For pig throat and nasal cartilage, the total yield is 5%.
