Abstract
  • A ?-cyclodextrin (?-CD) modified electrokinetic micellar capillary chromatography (MEKC) method was used for the enantiomer separation of a racemic trans-1,2-dihydro-1,2-dihydroxy-chrysene (chry-trans-1,2-diOH) mixture. The chiral resolution was strongly influenced by several important parameters: surfactant concentration and addition of organic modifier to the background electrolyte (BGE). An optimized electrophoretic system was used, consisting of the following conditions: 25 mM phosphate buffer, pH 7.8, 50 mM sodium dodecyl sulfate, 20 mM ?-CD, 7.4% v/v 2-propanol as BGE; the applied voltage, 18 kV, corresponded to 37 ?A at a constant temperature of 25°C. This electrophoretic method was applied for monitoring the chry-trans-1,2- diOH enantiomer formation in a real sample, obtained from in vitro metabolic activation of chrysene by phenobarbital-?-naphthoflavone-induced rat microsomes. The (+) and (-) enantiomers were identified by the racemate and the single enantiomer standard addition method and by spectra comparison with the synthetic compound. Under the experimental conditions used for chrysene activation, the (+) optical isomer was the prevailing form. The CD-MEKC system showed high reproducibility and selectivity, allowing a fast and interference-free analysis even of the in vitro metabolic sample extract, without any pretreatment. (literal)
