RESUMO

Due to the threat of extinction of Amburana cearensis, a tree of medicinal importance for the Northeastern Brazil, a phytochemical analysis was performed with specimens obtained by seed germination. Ten compounds were isolated and identified by spectroscopic methods and comparison with literature data. p-Hydroxybenzoic acid, ayapin, (E/Z)-melilotosides are being reported for the first time for the genus, besides coumarin, isokaempferide, vanillic acid, protocatechuic acid, amburosides A and B which have already been found in the trunk bark. Based on physical and NMR spectroscopy evidences the structures of several melilotosides already described in the literature have been suggested to be revised.
