摘要
目的:建立药物马来酸氨氯地平的化学结构确证方法。方法:通过高效液相色谱(HPLC)测定纯度;热分析(TA)、红外光谱(IR)、核磁共振(NMR)、元素分析(EA)以及X射线粉末衍射(XRD)等分析手段测定结构。结果:证实马来酸氨氯地平的结构为3-乙基-5-甲基-2-(2-氨乙氧甲基)-4-(2-氯苯基)-1,4-二氢-6-甲基-3,5-吡啶二羧酸酯顺丁烯二酸盐。结论:本法测定结果准确,为马来酸氨氯地平的生产和鉴定提供了较为全面的参考数据。
Objective: To establish a method for the determination of the chemical structure of Amlodipine maleate. Method: High - performance liquid chromatography ( HPLC ), thermal analysis ( TA), Fourier transform spectroscopy ( FT- IR), nuclearmagnetic resonance (NMR), elemental analysis (EA), and the X- ray powder diffraction(XRD) were adopted to analyze the chemical structure of Amlodipine maleate. Result :The structure of Amlodipine maleate is2 - [ (2 - Aminoethoxy) methyl ] - 4 - (2 - chlorophenyl) - 1,4 - dihydro - 6 - methyl - 3,5 - pyridin- edicarboxylic acid 3 - ethyl 5 - methyl ester (Z) - 2 - butenedioate. Conclusion: The result of the method is accurate,general and can provide a comprehensive reference for production and identification of Amlodipine maleate.
