Enantiomeric determination of amphetamine and methamphetamine in urine by precolumn derivatization with Marfey's reagent and HPLC.
An analytical method was developed for enantiomeric determination of amphetamine and methamphetamine in human urine. The enantiomers were isolated from urine by solid-phase extraction, and diastereomers were formed by derivatization with the chiral Marfey's reagent (1-fluoro-2,4-dinitrophenyl-5-l-aniline amide). The diastereomers were separated by reversed-phase high-performance liquid chromato...
متن کاملSimultaneous Determination of Triazolam and Its Metabolites in Human Blood and Urine by Gc/ms
A sensitive and selective method has been developed for simultaneous determination of triazolam and its major metabolites, a-hydroxytriazolam and 4-hydroxytriazolam in human whole blood and urine. The drugs were effectively extracted using a 3-step solvent extraction procedure followed by tert-butyldimethylsilyl derivatization, and subjected to GC/MS in the negative ion chemical ionization mode.
