Abstract: Fabaceae is represented in the Amazon region by a high diversity of species and genera that have economic and agroecological importance; however, there is a lack of phytochemical studies. Using LC-DAD-SPE/NMR, analyses of fractions of the methanolic extract from wood residues were performed, and a bipterocarpan (medicarpine-7-O-7′′ secundiflorol I) was identified for the first time. In addition, the known flavonoids 7,3′-dihydroxy-4′-methoxypterocarpan, nissolin, medicarpin, and biochanin A from Andira parviflora Ducke heartwood, the flavonoids taxifolin, butin, 3-methoxyquercetin, and a new derivative of menthiafolic acid (dapaznide) from Inga alba (Sw.) Willd. trunk wood were also identified. Thus, this study has brought new information on the secondary metabolism of both forest species, as well as adding to our knowledge regarding their wood residues. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
