    • Abstract

       

      By the action of methyl iodide and potassium carbonate, quercetin underwent complete methylation, while herbacetin and gossypetin yielded 3∶7∶8∶4′-tetramethyl ether and 3∶7∶8∶3′∶4′-pentamethyl ether respectively. This reagent, therefore, resembles diazomethane in the methylation of the naturally occurring flavonols.
