摘要
目的建立HPLC法测定甲磺酸伊马替尼原料药的含量。方法采用ZorbaxSB—C18色谱柱(250mm×4.6mm,5μm),柱温30℃,流动相为乙腈-水-三乙胺(22:77:1,首先配制三乙胺水溶液,用85%磷酸调pH3.5),流速1.1mL·min-1,检测波长268nm,进样体积20μL。结果甲磺酸伊马替尼原料药5~500μg·mL-1与峰面积呈良好的线性关系(r=0.9999,n=10),检测限1ng·mL-1,平均回收率及RSD分别为99.82%、0.2%(n=9)。结论所用方法灵敏准确,可为甲磺酸伊马替尼原料药的质量控制提供试验依据。
OBJECTIVE To develop an HPLC method for the content determination in the raw material of Imatinib mesylate. METHODS An Zorbax SB -C18 column(250 mmx 4.6 mm ,5 μm)was used with a mobile phase of aeetonitrile -water- triethyl- amine(22 : 77 : 1 ), and the aqueous solution of triethylamine was adjusted to pH3.5. The detection wavelength was set at 268 nm, the column temperature was 30 ℃ ,and the flow rate was 1.1 mL.min-1. The injection volume was 20 μL. RESULTS The linear range of lmatinib mesylate was 5 - 500 μg mL- 1 (r= 0. 9999, n = 10). The detection limit for Imatinih mesylate was 1 ng. mL - 1. The average recovery of Imatinib mesylate was 99.82% ( RSD = 0.2% , n = 9 ). CONCLUSION The method is simple, reliable, accurate and very suitable, which can be used for the content determination of Imatinib mesylate.
