    • Abstract


      Para oxidation in the side-phenyl nucleus has now been investigated using potassium persulphate and 3′-hydroxy-3:5:7:4′:5′-pentamethoxy flavone obtained conveniently from cannabiscitrin. The resulting quinol on methylation yields 3:5:7:3′:4′:5′:6′-heptamethoxy flavone and on demethylation 6′-hydroxy myricetin which is the first example of a flavone having four hydroxyl groups in the side-phenyl nucleus.
