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.
