Abstract
The invention belongs to the field of analytical chemistry, and particularly relates to a method for determining related substances in alanyl-glutamine or a preparation thereof, and the method adopts HPLC (High Performance Liquid Chromatography) for detection. Wherein a chromatographic column takes octadecyl acylamino bonded silica gel as a filling agent and takes a sodium octanesulfonate solution-acetonitrile (95: 5) as a mobile phase. The method can effectively separate nine related substances of the alanyl-glutamine, is good in specificity and high in sensitivity, and can realize accurate and quantitative determination of the alanyl-glutamine or a preparation of the alanyl-glutamine.
Description
technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to a method for measuring alanyl glutamine and related substances in preparations thereof by high performance liquid chromatography. Background technique [0002] Alanyl glutamine, the structural formula is as follows: [0003] [0004] It is an amino acid drug commonly used in clinical practice. It has the functions of supplementing essential amino acids for nutrition, maintaining acid-base balance in the body, and enhancing the body's immunity. Many domestic companies have been approved to use this raw material drug in the marketed preparations, such as: Evonik Maxsi Simplified Co., Ltd., Shandong Chenlong Pharmaceutical Co., Ltd., Wuhan Daan Pharmaceutical Co., Ltd., etc. [0005] Impurity research is an important way to evaluate the quality of drugs. Alanyl glutamine may introduce residual raw materials and other related substances during the synthesis process...
