title: Gas chromatographic procedure for simultaneous determination of selegiline metabolites, amphetamine, methamphetamine and demethyl-deprenyl in pig plasma.
abstract: A sensitive assay for the simultaneous quantitative determination of amphetamine, methamphetamine and demethyl-deprenyl in pig plasma is described. NP-Gas chromatography is used to determine the extracted plasma concentrations of the three target compounds as their N-penta-fluoro-benzoyl derivatives. Quantitation is performed using 1-phenyl-2-pentylamine as internal standard. The derivatives are separated on a phenyl-methylsilicone capillary column. Quantitation limit for each target compound was 1.2 ng ml-1. Levels of amphetamine, methamphetamine and demethyl-deprenyl have been determined in plasma of pigs treated with Selegiline in different formulations and doses.
