High Performance Liquid Chromatographic Determination and Content Uniformity of Aclatonium Napadisilate Preparation

고속액체 크로마토그라프법을 이용한 제제중 Aclatonium Napadisilate의 정량 및 함량균일성에 관한 연구

A convenient high performance liquid chromatographic method was established for the quantitative determination and content uniformity test of aclatonium napadisilate preparation. This method was more simple to make the sample solution for injection, and easy to determine the content in the preparation. Aclatonium napadisilate was chromatographed using a $Lichrosorb-NH_2$ column $(4mm\;{\times}\;25\;cm$, and acetonitrile-water mixture (83:17) as an eluent at a flow rate of 1.8 ml/min. RI-detector response was linear over a range of $0.5{\sim}2.0%$ aclatonium napadisilate under above conditions. Reproducibility studies gave relative standard deviation of 1.29%.
