| titleOfInvention | Method for synthesizing citicoline sodium by using cytidine enzymatic method |
| abstract | The invention discloses a method for synthesizing citicoline sodium by a cytidine enzymatic method. And when the reaction conversion rate is more than 99%, heating and filtering the reaction solution, carrying out nanofiltration, concentrating, purifying by using a column, concentrating the eluent, adding 95% ethanol, crystallizing to obtain a crude product of citicoline sodium, and further refining the crude product to obtain a finished product of citicoline sodium. The HPLC purity of the finished product is more than 99 percent, and the total yield is more than 90 percent. |
