| metadata.dc.description.resumo: | Duas novas flavonas, 5 -hidroxi -7,5' -dimetoxi -3',4' -metilenodioxiflavona e 5 -hidroxi -7,3',5' -trimetoxi -4' -(3,3 -dimetilaliloxi) flavona foram isoladas das folhas de Ficus gomelleira, juntamente com três flavonas conhecidas, a 5,6,7,3',4',5' -hexametoxiflavona, 5 -hidroxi -8,3',4' -trimetoxi -2'',2'' -dimetilpirano (5",6":6,7) -flavona e 5 -hidroxi -8,3',4',5' -tetrametoxi -2'',2'' -dimetilpirano (5",6":6,7) -flavona. As estruturas das substâncias isoladas foram elucidadas com base na análise de seus dados espectrais, bem como por comparação com dados da literatura. |
| 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. |
