| titleOfInvention | Method for preparing chondroitin sulfate and its sodium salt from shark bone or cartilage |
| abstract | The present invention relates to a method for producing chondroitin sulfate and its sodium salt represented by the following formula (1) from dried shark bone or cartilage, ① by immersing the shark bone or cartilage in hydrochloric acid solution, washed with 95% ethanol Removing impurities; ② extracting chondroitin sulfate from shark bone or cartilage using protease; ③ adjusting the pH of the extract to about 8.5 to remove proteins other than chondroitin sulfate; ④ purifying the extract using an ion exchange resin; ⑤ adjusting the pH of the extract passed through the ion exchange resin to 5.0 to 7.0, if necessary, and then dissolving it completely by adding sodium salt; And ⑥ crystallizing chondroitin sulfate or its sodium salt using alcohol.n n n n n n n n n n N: 75 to 85 M: H or Na |
