Abstract

The invention discloses a detection method of enoxaparin sodium. The detection method of the enoxaparin sodium comprises the following steps of a, taking anenoxaparin sodium sample, and carrying out hydrolysis to obtain a hydrolysis solution; b, taking the hydrolysis solution, and carrying out derivatization to obtain a solution to be detected; c, adopting a high performance liquid chromatography method to detect the solution to be detected, detecting to obtain a peak area of glucosamine and mannosamine, and calculating to obtain the proportion of the glucosamine and the mannosamine. According to the detection method provided by the invention, the proportion of the glucosamine and the mannosamine is detected, so that the product quality and/or the stability of the production process can be reflected intuitively; in addition, the detection method is simple and convenient, does not need to adopt a complicated gradient elution program so as to realize accurate detection on the enoxaparin sodium, and provides a novel simple and practical method for monitoring the product quality and/or the stability of the production process of the enoxaparin sodium.

Description

technical field [0001] The invention relates to a method for detecting enoxaparin sodium. Background technique [0002] Enoxaparin sodium, as an anticoagulant used for the prevention and treatment of deep vein thrombosis or pulmonary embolism, its product quality is directly related to the life safety of patients. [0003] In the production process of enoxaparin sodium, if the production technology of the enterprise is not advanced or the control level is not high, the quality of its products is likely to fluctuate greatly; therefore, in order to monitor the product quality of enoxaparin sodium and / or The stability of its production process, and at the same time, in order to minimize the economic loss caused by product quality fluctuations, it is necessary to detect the produced enoxaparin sodium. [0004] However, the existing detection methods of enoxaparin sodium: Chinese patents CN102323355A and CN104193849A, when detecting enoxaparin sodium, more than 10 chromatographi...
