Methods The hair samples were treated by sodium hydroxide solution, and acylated by trifluoroacetic anhydride, and then determined by gas chromatography-mass spectrometry. The column was HP-5 MS(30 m×0.25 mm i.d. ×0.25 μm), and the mobile phase was helium. The flow rate was 1 mL·min-1, and the column temperature gradient were 80 ℃ for 2 min, increased to 180 ℃ at 30 ℃·min-1, then increased to 210 ℃ at 10 ℃·min-1, then increased to 280 ℃ at 30 ℃·min-1, and maintained for another 10 min. The temperature of the ion source, the quadrupole, and the injector port were 280 ℃, 230 ℃, and 200 ℃, respectively. The injection volume was 1 μL, and the electron impact source was used. The single ion monitoring mode was used to quantitatively analyze the ions as m/z 118(amphetamine),m/z 154(methamphetamine),m/z 162(3,4-methylenedioxyamphetamine),and m/z 162(3,4-methylenedioxymethamphetamine). Results The standard curve of amphetamine was y = 3. 36 e+000 x + 6. 08 e-002(r =0. 999),the linear range was 1. 5-150 ng·mg-1. The standard curve of methamphetamine was y = 3. 38 e+000 x +9. 35 e-002(r = 0. 999), the linear range was 1. 5-150 ng · mg-1. The standard curve of 3,4-methylenedioxyamphetamine was y = 2. 49 e+000 x + 2. 44 e-002(r = 0. 999),the linear range was 1. 5-150 ng·mg-1.And the standard curve of 3,4-methylenedioxymethamphetamine was y = 2. 90 e+000 x + 6. 38 e-002(r = 0. 999),the linear range was 1. 5 ~ 150 ng·mg-1. The intra-day and inter-day precisions were between 1. 97% and 9. 18%.The accuracy was between 94. 28% and 107. 78%,and the average extraction recoveries of the four analytes were greater than 85. 00%,and the stability was good. Conclusion The method was simple,sensitive as well as specific,which can be applied for the determination of Amphetamines of hair samples of drug abusers.
