Abstract
  • In this work,the simultaneous enantioseparation of the second-generation antidepressant drug mirtazapine and its main metabolites 8-hydroxymirtazapine and N-desmethylmirtazapine by chiral CEC isreported.The separation of all enantiomers under study was achieved employing a capillary column packed with a vancomycin-modified diolstationary phase. With the aim to optimize the separation of the three pairs of enantiomers in the same run,different experimental parameters were studied including the mobile phase composition (buffer concentration and pH,organic modifier type and ratio,and water content),stationary phase composition,and capillary temperature. A capillary column packed with vancomycin mixed with silica particles in the ratio(3:1)and a mobile phase composed of 100 mM ammonium acetate buffer(pH6)/HO2/MeOH/ACN(5:15:30:50)allowed the complete enantioresolution of each pair of enantiomers but not the simultaneous separation of all the studied compounds. For this purpose,a packing bed composed of vancomycin-CSP only was tested and the baselineresolution of the three couples of enantiomers was achieved in a single run in less than 30 min,setting the applied voltage and temperature at 25 kV and 207 C,respectively.In order to show the potential applicability of the developed CEC method to biomedical analysis, a study concerning precision, sensitivity, and linearity was performed. The method was then applied to the separation of the enantiomers in a human urine sample spiked with the studied compounds after suitable SPE procedure with strong cation-exchange(SCX)cartridges.
