    • Abstract

       

      2-Hydroxy-6-methoxy benzoic acid condenses with orcinol giving rise to (1) 1-hydroxy-3-methyl-8-methoxy xanthone and (2) 1: 8-dihydroxy-3-methyl xanthone. The second is also obtained from γ-resorcylic acid. The first undergoes nuclear oxidation with alkaline persulphate to yield ravenelin-8-methyl ether which is demethylated to ravenelin.
