CANUTO, Kirley Marques e SILVEIRA, Edilberto Rocha. Chemical constituents of trunk bark of Amburana cearensis A.C. Amith. Quím. Nova [online]. 2006, vol.29, n.6, pp. 1241-1243. ISSN 0100-4042. http://dx.doi.org/10.1590/S0100-40422006000600018.
The phytochemical analysis of the ethanol extract trunk bark of Amburana cearensis allowed the isolation and identification of twelve constituents: coumarin, sucrose, two phenol acids (vanillic acid and protocatechuic acid), five flavonoids (afrormosin, isokaempferide, kaempferol, quercetin and 4'-methoxy-fisetin), a phenol glucoside (amburoside A) and a mixture of glucosilated b-sitosterol and stigmasterol. Their structures were elucidated by spectroscopic methods such as IR, MS, 1H and 13C NMR, including uni and bidimensional techniques, in addition to comparison with literature data.
