Abstract

The purple colour produced by treatment of cannabidiol (I) with 5% ethanolic potassium hydroxide (Beam test) is due to the anions of the hydroxy-quinone II and its dimer III. Compounds II and III are formed from I by air oxidation during the reaction. The quinone III is reduced in the mass spectrometer to a M+ + 4 species (probably the dihydroquinone).
