    • Abstract

       

      The constitution of patuletin as 6-O-methyl quercetagetin has been finally established by the study of its penta-ethyl ether which yieldsO-diethyl-protocatechuic acid and ω∶4∶6-triethoxy-5-methoxy-2-hydroxy-acetophenone on degradation with alkali. The above ketone andO-pentaethylpatuletin have been synthesised by unambiguous methods starting from ω-ethoxy-phloroacetophenone.
