| titleOfInvention | Mesalazine enema related substance determination method |
| abstract | The invention provides a method for measuring related substances of mesalazine enema and discloses a method for analyzing related substances of mesalazine enema. The method adopts high performance liquid chromatography, uses octadecylsilane chemically bonded silica as chromatographic column filler, adopts an ultraviolet detector, selects proper organic phase, buffer solution and water as mobile phase, and adopts gradient elution, thereby effectively solving the separation problem of mesalazine and impurities. The method has strong specificity and good repeatability, and can ensure the controllability of the process and the degradation impurities in the mesalazine. |
