Résumé : |
The 1H NMR profiles of 13 samples of e-liquids supplied by French customs were obtained with high-field and low-field NMR. The high-field 1H NMR spectra allowed the detection of matrix signals, synthetic cannabinoids, and flavouring compounds. Quantitative results were obtained for the five synthetic cannabinoids detected: JWH-210, 5F-MDMB-PICA, 5F-ADB, 5F-AKB48, and ADB-FUBINACA. Conventional GC-MS analysis was used to confirm compound identification. Fluorine-19 NMR was proposed for the quantification of fluorinated synthetic cannabinoids and was successfully implemented on both 400 MHz and 60 MHz NMR spectrometers. This study based on few examples explored the potentiality of low-field NMR for quantitative and quantitative analysis of synthetic cannabinoids in e-liquids.
Highlights: • NMR was applied to the analysis of e-liquids containing synthetic cannabinoids. • The 1H NMR profiles of 13 samples of e-liquids were obtained with HF and LF NMR. • Fluorinated synthetic cannabinoids were quantified using HF and LF 19F NMR. • Quantitative results were obtained for the five synthetic cannabinoids detected. |
