Abstract
A method for the detection of 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid, one of the predominant metabolites of Δ9-tetrahydrocannabinol in human urine, is presented. As screening method a homogeneous enzyme immunoassay is used (Emit dau). Positive results are confirmed by GLC/MS as alternative method. After glucuronide hydrolysis the metabolite is isolated using a C18 reversed phase column and methylated in the 1-hydroxy and 9-carboxy position. The methylated metabolite is detected by gas chromatography/mass fragmentography. This pretty rapid method seems to be useful in forensic routine analysis. Es wird eine Methode zum Nachweis von 11-Nor-Δ9-tetrahydrocannabinol-9-carbonsäure, einem Hauptmetaboliten von Δ9-Tetrahydrocannabinol, im Urin beschrieben. Als Screening dient der Enzymimmunoassay (EMIT dau). Bei positivem Befund wird der Metabolit nach Glucuronidspaltung mit Hilfe einer C18-reversed phase-Säule isoliert und methyliert. Der Nachweis erfolgt mittels Massenfragmentographie. Das Verfahren ist für die forensisch-toxikologische Routineanalytik brauchbar.Keywords
