Plasma aromatic and sulfur containing amino acids are good indicators of protein anabolism/catabolism, while blood reduced and oxidized glutathione reflect oxidative status in an organism. Using a full factorial design for screening important variables (pH, concentration, temperature) we developed a capillary zone electrophoresis method permitting their measurements in the single run, without any derivatization procedures. The best separations were obtained within less than 30 min employing a 10 mmol/l phosphate buffer, pH 2.8, 18 degrees C, 15 kV voltage. Fairly good precision with a linear relationship between peak area and concentrations (r=0.995-0.999) were obtained. The method was used to analyze human capillary blood.
