8-hydroxycannabinol: a new metabolite of cannabinol formed by human hepatic microsomes

Abstract  Metabolism of cannabinol (CBN) was studied in vitro using hepatic microsomes from human livers. The metabolites formed were analyzed by thinlayer chromatography (TLC) and identified by gas chromatography-mass spectrometry as their trimethylsilyl derivatives. 11-Hydroxy-CBN, the major metabolite, was detected together with a smaller amount of another mono-hydroxylated metabolite. The minor metabolite was identified as 8-hydroxy-CBN, after comparing its Rf value by TLC, retention time by GC, and the mass spectrum with those of the authentic compound. 8-Hydroxy-CBN was confirmed to be a new metabolite of CBN formed by human hepatic microsomes.
