Resumo

A gas chromatographic-mass spectrometric method is described for the analysis of 1-methyl-1,2,3,4-tetrahydro-β-carboline in alcoholic beverages. The analytical procedure involves the addition of semicarbazide and a deuterated analogue as the internal standard, followed by extraction with tolueneisoamyl alcohol and derivatization with pentafluoropropionic anhydride. Multiple ion detection showed 1-methyl-1,2,3,4-tetrahydro-β-carboline to be present in alcoholic beverages prepared by fermentation processes. The range of concentrations was 4·8-450 nmol/litre in wine and 9·1-69 nmol/litre in beer.
