Abstract
A rapid and specific method was developed to identify phenylethylamines in patient''s urine. After an organic extraction at appropriate pH, reverse phase ion-pair partition chromatographies were used, a high performance thin-layer test followed by high performance liquid chromatography [HPLC]. Uses and benefits of the procedure were described and compared with other methods. In 10 min the presence of phenylethylamine was detected on a thin-layer plate. In the case of positive result the product was then specificially identified by HPLC by a complete UV spectrum traced directly on the eluated compound. The sensitivity of the method was increased because the detection was operated at 215 nm.
