Resumo: | Phytochemical investigation of the resin of Amburana cearensis A. C. Smith allowed the isolation of a new compound: 3',4'-dimethoxy-1'-(7-methoxy-4-oxo-4H-cromen-3-yl)benzo-2',5'-quinone (1), together with six known compounds identified as: 4,2',4'-trihydroxychalcone (2), 7,8,3',4'-tetramethoxyisoflavone (3), 4,2',4'-trihydroxy-3-methoxychalcone (4), 3,4,5-trimethoxycinnamaldehyde (5), 3',4'-dimethoxy-7-hydroxyisoflavone (6) and 6,7,4'-trimethoxy-3'-hydroxyisoflavone (7). The structures were established from the IR, HR-ESI-MS and NMR spectral data, including 2D-NMR experiments. |
