Identification of 1-butyl-3-(1-(4-methyl)naphthoyl)indole in a herbal mixture

Besides the cannabinoid mimetic JWH-073, a novel 4 methylnaphthoyl homologue of JWH-073 was detected in a herbal mixture. The structure of the compound was elucidated after thin layer chromatographic enrichment from the herbal mixture by nuclear magnetic resonance (NMR) and gas chromatographic mass spectrometric (GC–MS) analysis. The paper outlines data after GC–MS, liquid chromatography mass spectrometry (LC–MS) and NMR spectroscopy, and describes the structure elucidation.
