Abstract

Homologs of Δ⁹-tetrahydrocannabinol (THC; Ic), cannabidiol (CBD; IIc) and cannabinol (CBN, IIIc) having butyl, rather than pentyl, side chains on the aromatic ring were identified by gas chromatography/mass spectrometry as minor constituents of marijuana samples that also contained propyl cannabinoids. The mass spectra of butyl-THC (Ib), butyl-CBD (IIb), and butyl-CBN (IIIb) are analogous to those of the corresponding propyl and pentyl homologs and are consistent with the proposed structures.

Keywords:
forensic science, marijuana, cannabis sativa, cannabinoids, tetrahydrocannabinol, analogs, butyltetrahydrocannabinol, butlcannabinol, butylcannabidiol, gas chromatography/mass spectrometry, biosynthesis
