Popis: 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.
