发布时间:2018-08-03 12:25
【摘要】:为了建立一种检测甲磺酸奥希替尼含量的HPLC法,使用Agilent ZORBAX Eclipse Plus C_(18)色谱柱(4.6 mm×250 mm,5μm),流动相为甲醇-磷酸二氢钠缓冲液(pH 3.0)(50∶50),检测波长210 nm,柱温35℃,流速1.0 mL/min进行检测。甲磺酸奥希替尼浓度在分析物正常浓度的50%~150%(0.201 1~0.603 2 mg/mL)范围内与峰面积呈良好线性关系(r=0.999 9),最低检测限为0.08μg/mL,定量限为0.32μg/mL。3批样品的含量(%)分别为100.1、99.5和99.7。在所建立的色谱条件下,甲磺酸奥希替尼与各有关物质分离良好,包括部分工艺杂质及降解杂质。结果表明,所建立的方法专属、准确、简单、耐用,可用于奥希替尼原料的含量测定。
