    • Abstract

       

      The 6-methyl ether of euxanthone has been oxidised to 6-methoxy-1∶4-dihydroxy-xanthone by means of alkaline persulphate. By demethylation with hydriodic acid 1∶4∶6-trihydroxy-xanthone has been obtained. This compound and its derivatives differ from those obtained by Nierenstein by the oxidation of euxanthone itself with chromic acid and subsequent reduction.
