HPLC法测定阿苯达唑有关物质
Journal: Frontiers of Chinese Medicine Research DOI: 10.12238/fcmr.v6i3.9254
Abstract
目的:探讨阿苯达唑有关物质的HPLC测定方法,方法:采用Welch AQ 250m*4.65μm色谱柱,梯度洗脱,流动相A:0.01mol.L-1乙酸铵(用甲酸调节pH至2.2),流动相B:甲醇,流速为1ml.min-1,波长为254nm与292nm。结果:阿苯达唑与各杂质有效分离,12个杂质在1~7μg.ml-1浓度范围内线性良好,回收率均在80%~120%之间。结论:该方法首次将阿苯达唑及12个已知杂质有效分离,方法简便,专属性强,可作为产品的质量检测方法。
