Characterization of the butyl homologues of Δ1‐tetrahydrocannabinol, cannabinol and cannabidiol in samples of cannabis by combined gas chromatography and mass spectrometry

Abstract

The butyl homologues of Δ1‐tetrahydrocannabinol, Δ1‐tetrahydrocannabinolic acid, cannabinol and cannabidiol have been identified in several samples of cannabis. 8 samples contained Δ1‐tetrahydrocannabinolic acid, one sample contained cannabinol and one sample contained both cannabinol and cannabidiol. Separation by gas chromatography and identification by gas chromotography‐mass spectrometry was achieved by the preparation of trimethylsilyl, d9‐trimethylsilyl, triethylsilyl and tri‐n‐propylsilyl derivatives.
