Abstract:
Objective A rapid and highly sensitive method, based on the high performance thin-layer chromatography, was described for the qualitative and semiquantitative determination of 7-aminon-itramepam, the main metabolites of nitramepam, in human urine. Method 7-aminonitramepam was extracted by diethyl ether under pH9 condition. Fluorecsamine was used as a reagent to produce fluorescent product to show analyte on plate. Results The limit of detection for 7-aminonitramepam in urine was 5ng/ ml and the limit of quantitation was 15ng/ml. Conclusion The method can be successfully used for determining 7-aminonitramepam in urine samples excreted over 48h period after receiving 10mg nitramepam o-rally and could be applied to drug examination for the cases of drug-facilitated rob.
