Zusammenfassung:Gas chromatography-mass spectrometric (GC-MS) procedure is presented for the simultaneous qualification and quantitation of methamphetamine (MA), amphetamine (AMP), 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), and 3,4-methylenedioxyethylamphetamine (MDEA) in human hair. The method procedure involves decontamination of hair with distilled water and acetone, acidic hydrolysis, extraction in the presence of deuterated internal standards, and GC-MS analysis after derivatization with trifluoroacetic anhydride (TFAA) in ethylacetate. The limit of detection for 5 drugs were about 0.1∼0.15 ng/mg using 30 mg hair sample. Coefficient variations of correlation ranged from 0.9941 to 0.9993. The recoveries of these drugs were found to be 93.4∼104.4%. The concentrations of AMP, MA, MDA, and MDMA in abusers' hair samples were measured 0.17∼2.88, 2.09∼18.34, 0.24∼3.83, and 3.10∼22.81 ng/mg, respectively. The ratios of MA/AMP and MDMA/MDA ranged 5.67∼49.57 and 4.78∼54.31, respectively. This assay has been successfully utilized in the evaluation of the deposition of amphetamine-type stimulants (ATS) in human hair.
