[Some analytical aspects of mescaline].

Abstract

Mescaline was extracted from a vegetal powder, seazed on the "Côte d'Azur", then analyzed by several techniques (thin layer chromatography, infra-red spectrometry, gas chromatography/mass spectrometry) and determined by high performance liquid chromatography with methyl-amphetamine as internal standard. The powder contained 0.76% of mescaline. The presence of a possible isomer was noted in the powder as well as in a "old" sample of mescaline.
