Flavones from the Leaves of Ficus gomelleira

Abstract

Two new flavones, 5-hydroxy-7,5′-dimethoxy-3′,4′-methylenedioxyflavone and 5-hydroxy-7,3′,5′-trimethoxy-4′-(3,3-dimethylallyloxy)flavone, as well as three known flavones: 5,6,7,3′.4′,5′-hexamethoxyflavone, 5-hydroxy-8,3′,4′-trimethoxy-2″,2″-dimethylpyrano (5″,6″:6,7)-flavone and 5-hydroxy-8,3′,4′,5′-tetramethoxy-2″,2″- dimethylpyrano (5″,6″:6,7)-flavone were isolated from the leaves of Ficus gomelleira. Their structures were elucidated by spectroscopic methods and comparison with literature data.
