The purpose of this study, the direct separation of aminoalkanol derivatives I and II of 1,7-dimethyl-8,9-diphenyl-4-azatricyclo[5.2.1.0(2,6)] dec-8-ene-3,5,10-trione, which was found in earlier studies as potential anticancer drugs, were performed. Capillary electrophoresis offers the possibility of fast, cheap, and reproducible separations for compounds I and II. In this paper, the simultaneous separation of I and II by capillary zone electrophoresis has been achieved within 8min by use of 50 mM phosphate buffer of pH 2.5. Analysis of the two compounds in the serum plasma standards was conducted. Limits of detection of I and II by UV absorbance at 200 nm were achieved in the range of 156.3-156.6 ng/mL. The method was validated for linearity, accuracy, precision, limits of detection, and quantification. The calibration equation revealed a good linear relationship (r(2) = 0.998-0.999). Sufficient recovery was observed in the range of 96.3-99.5%. The method showed good reproducibility with intra-and interday precision of 0.97 and 1.76%, respectively. The quantification limits for the compounds were in the range of 477.0-479.8 ng/mL. The proposed method was applied to the analysis of real serum samples.
