| heal.abstract | A gas chromatographic method is described for the quantification of free and total malondialdehyde (MDA) in biological materials, The procedure involves derivatization of the analyte with 2,4,6-trichlorophenylhydrazine, extraction with n-hexane, and separation of the cyclic derivatization product on a OV-5 gas chromatographic column. Concentration of the derivatization reagent, pH, reaction time, and temperature were investigated to determine the optimal derivatization conditions. Under these conditions, the method allows for the selective detection of free and total MDA at femtomole levels in several biological materials without any interferences. The procedure yields relative standard deviation values for the intra- and interassays in the range 3.3 and 3.9%, respectively, for the electron-capture and mass-selective (SIM mode) detection systems. Recoveries of MDA from spiked matrices reached 96%. The present method offers the advantage of the alternative use of either electron-capture or mass-selective detection, Furthermore it avoids overestimation of MDA since it employs mild conditions for sample processing and there is no need for preventing protein separation for the assessment of free MDA.
