Abstract

A stereospecific HPLC method has been developed for the resolution of the enantiomers of salbutamol in human urine. After solid-phase extraction and derivatization with (S)-(-)-alpha-methylbenzyl isocyanate, the diastereomeric derivatives were resolved (R(s)=1.59) on 5 mum octadecylsilan column using 47% methanol as a mobile phase with fluorescence detection. The detection limit of each enantiomer was 10 ng/ml (S/N=3).
