摘要

In the analysis of ephedrine (EP) by gas chromatography/mass spectrometry (GC/MS), methcathinone (MC), a narcotic, has been detected as its artifact, and we investigated the formation mechanism of MC from EP. The effective analytical procedure which allows us to prevent its formation has been also examined. The injection temperature of the GC instrument was varied with different extraction solvents from aqueous EP solution, and the amount of MC as the artifact was measured.
