PMID- 16580268 OWN - NLM STAT- MEDLINE DCOM- 20060619 LR - 20191210 IS - 1570-0232 (Print) IS - 1570-0232 (Linking) VI - 835 IP - 1-2 DP - 2006 May 1 TI - A validated gas chromatographic-electron impact ionization mass spectrometric method for methylenedioxymethamphetamine (MDMA), methamphetamine and metabolites in oral fluid. PG - 90-9 AB - An analytical method to simultaneously quantify amphetamine (AMP), methamphetamine (MAMP), methylenedioxymethamphetamine (MDMA), methylenedioxyamphetamine (MDA), methylenedioxyethylamphetamine (MDEA), 3-hydroxy-4-methoxy-methamphetamine (HMMA) and 3-hydroxy-4-methoxy-amphetamine (HMA) in oral fluid is presented. Four hundred microlitres of oral fluid collected via expectoration was extracted by solid phase extraction. GC/MS-EI with selected ion monitoring (SIM) yielded linear curves 5-250 ng/mL for AMP, MAMP, MDMA and MDEA, 5-500 ng/mL for MDA and 25-1,000 ng/mL for HMA and HMMA. Recoveries were greater than 85%, accuracy 87-104%, and precision less than 8.3% coefficient of variation. This assay will be used to investigate distribution of sympathomimetic amines into human oral fluid following controlled drug administration.
