Resumo
In recent years, the interest in the propagation of native forest species has intensified with the aim of recovering degraded areas and the restoration of the landscape. As such, some species of Fabaceaeare considered promising woody species for planting in reforestation programs and agroforestry systems. In the present paper, the authors complement the need for studies related to secondary metabolites of the woody speciesHymenaea courbaril L. Platymiscium ulei Harms and Hymenolobium petraeum Ducke. Thus, the phytochemical study of H. courbaril led to the isolation and identification of diterpenes eperuic acid (1) and methyl eperuate (2); triterpenes oleanolic acid (3) andhederagenin(8); flavonoides quercetin (4), fisetinediol (5), liquiritigenin (6) and 3-methoxy-5,7,3',5'-tetrahydroxyflavanonol (7).P. ulei gave pterocarpane homopterocarpin (9) and coumarin scoparone(10); H. petraeum gave isoflavan sativan (11), in addition to the amino acidtyrosine(12). Flavonoids were the predominant constituents in the three species of Fabaceae; however, the presence of isoflavonoids in Platymiscium ulei and Hymenolobium petraeum is probably associated with the resistance of this high density wood to pathogenic fungi.
