Abstract

The invention discloses a method for determining content of rosuvastatin calcium and related substances thereof by employing an HPLC (high performance liquid chromatography) method. By adopting the method, octadecylsilane chemically bonded silica is selected as a chromatographic column of a filler, and a mobile phase is formed by methanol and water (containing 0.1-0.8% of trifluoroacetic acid). The content of the rosuvastatin calcium and the related substances thereof can be accurately determined under a chromatographic condition, so that the quality of materials and preparation of the rosuvastatin calcium is well controlled.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a method for determining the content of rosuvastatin calcium and its related substances by HPLC. Background technique [0002] Rosuvastatin is a selective HMG-CoA reductase inhibitor that can regulate blood lipids. Usually exists in the form of its calcium salt, the molecular formula is C 44 h 54 CaF 2 N 6 o 12 S 2 , the chemical name is bis-(E)-7-[4-(4-fluorophenyl)-6-isopropyl-2-[methyl(methylsulfonyl)amino]-pyrimidin-5-yl]( 3R,5S)-3,5-hydroxy-6-heptenoic acid] calcium salt. AstraZeneca's sales of rosuvastatin calcium in 2012 reached USD 6.253 billion, and the drug has a good market and application prospect. [0003] [0004] Rosuvastatin calcium has two chiral centers, is unstable in nature, and is prone to degradation, etc. Therefore, it is necessary to establish a determination method for its content and related substances to ensure the quality control of the f...
