Abstract:Micellar electrokinetic capillary chromatography was used to separate levodopa (L-3,4-dihydroxyphenyl-L-alanine), dextrodopa (D-3,4-dihydroxyphenyl-L-alanine) andDL-3-O-methyl-dopa, a metabolite of dopa, which were derivatised with the Marfey's reagent, in sodium borate, sodium dodecyl sulfate and acetonitile buffer system. WhereasDL-dopa derivatives could be separated,DL-3-O-methyl-dopa derivatives could not.
Keywords:levodopa   dextrodopa     font-variant: small-caps"  >dl-3-O-methyl-dopa   micellar electrokinetic capillary chromatography
