Abstract

The invention relates to a rapid, simple, convenient and sensitive detection method for related impurities of glucosamine salt medicines, which is characterized in that the detection is performed according to high performance liquid chromatography in pharmacopoeia of the people's republic of China (Edition 2010). A chromatographic condition and system adaptability test comprises the steps of: adopting an amino column as a detection column; preparing a phosphate buffer solution, wherein 0.7 g of KH2PO4 is diluted to 1000 ml by adding water and the pH value is adjusted to be 7.5 by adding a stronger ammonia water solution; adopting the phosphate buffer solution and acetonitrile as a mobile phase, wherein the volume ratio of the phosphate buffer solution to the acetonitrile is 35:65; and detecting wavelength of 195 mm, the flow rate of 1.0 ml / min, the column temperature of 35 DEG C, and the theoretical plate number of not less than 800in the terms of glucosamine hydrochloride . The method overcomes the characteristics of poor sensitivity and poor specificity and the like in the detection by adopting a thin layer detection method in the prior art.

Description

technical field [0001] The invention relates to a method for detecting related impurities in glucosamine salt medicines, in particular to a fast, simple and sensitive detection method for related impurities in glucosamine salt medicines. Background technique [0002] Glucosamine salt drugs (such as glucosamine hydrochloride, glucosamine sulfate sodium chloride and glucosamine sulfate potassium chloride, etc.) are currently a very popular type of bone and joint nutritional supplements in the world, and many countries have approved it as a bone and joint nutritional supplement. Drugs for joint disease. The US FDA included it in the Pharmacopoeia as early as 1995, and the European Union included it in the Pharmacopoeia in 1999. After 1998, my country gradually established the raw materials of glucosamine hydrochloride, glucosamine sulfate sodium chloride and glucosamine sulfate potassium chloride. and its formulation standards. [0003] Glucosamine is a natural amino monosacch...
