| Popis: | In this research, new DABCO-based ionic liquid-modified Fe3O4 nanoparticles (NPs) were synthesized by the quaternization reaction. Modified magnetic NPs were characterized by different techniques. The functionalized magnetic NPs were utilized as a novel sorbent for magnetic SPE of imatinib mesylate (IMA) from human plasma samples followed with UPLC–MS–MS. Effective parameters on the extraction of IMA were studied by three-level Box–Behnken experimental design under response surface methodology. Under the optimized conditions, the proposed method was validated based on the principles of Guidance for Industry Bioanalytical Method Validation by the U.S. Food and Drug Administration. The linearity of the developed method was achieved within the range of 0.7–2500 ng mL−1. The LOD and lower limit of quantification were 0.68 and 0.21 ng mL−1, respectively. Satisfactory extraction recovery values ranged from 93 to 102% for human plasma samples with relative standard deviation values lower than 5.9%. The proposed analysis method was sensitive, efficient, rapid, and practical for the determination of IMA in biological samples. |
