超高效液相色譜-串聯(lián)質(zhì)譜法測定人血漿中尼洛替尼的研究
[Abstract]:Objective to establish a high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the determination of nilatinib in plasma. Methods carbamazepine was used as internal standard and protein precipitation was used. The chromatographic column consisted of ACQUITY UPLC BEH C18 (100 mm 脳 2.1 mm,1.7 渭 m),) mobile phase was acetonitrile-0.1% formic acid aqueous solution (35:65), and the flow rate was 0.4 mL min-1, positive ion mode multi-reaction monitoring (MRM) scanning analysis. The specificity, standard curve and lower limit of quantification, precision and recovery, matrix effect and stability were investigated. Results the linear range of nilotinib in plasma was 0.1 渭 g / mL ~ (-1) (r = 0.998), and the lower limit of quantification was 0.1 渭 g / mL ~ (-1). The recovery was 95.11 渭 g / mL ~ (-1) and the recovery rate was 101.32 渭 g / m ~ (-1). The relative standard deviation (RSD) of daytime precision was less than 15. Conclusion this method is simple, rapid, specific and sensitive. It can be used to monitor the concentration of nirotini.
