Surfactant-assisted electromembrane extraction combined with cyclodextrin-modified capillary electrophoresis for the separation and quantification of Tranylcypromine enantiomers in biological samples.
Journal of Separation Science 2018 January
Surfactant-assisted electromembrane extraction coupled with cyclodextrin-modified capillary electrophoresis was developed for the separation and determination of Tranylcypromine enantiomers in biological samples. This combination would provide a new strategy for selective and sensitive determination of target analytes. The addition of surfactant in the donor solution improved the analyte transport into the lumen of hollow fiber that resulted in an enhancement in the analytes migration into acceptor solution. Optimization of the variables, affecting proposed method, was carried out and best results were achieved with a 175 V potential as driving force of the electromembrane extraction, 2-nitrophenyloctylether as the supported liquid membrane, donor solution containing 0.2 mM Triton X-100 with pH 3 and 0.1 M HCl for acceptor solution. Then, the extract was analyzed using cyclodextrin-modified capillary electrophoresis method for separation of Tranylcypromine enantiomers. The best results were obtained with a phosphate running buffer (100 mM, pH 2.0) containing 7% w/v hydroxypropyl-α-cyclodextrin. Under the optimum conditions, a low limit of detection (3.03 ng/mL), good linearity (R2 > 0.9953), and relative standard deviations below 4.0% (n = 5) were obtained. Finally, this procedure was applied to determine the concentration of Tranylcypromine enantiomers in urine samples with satisfactory results.
