The genus Dipteryx, to which the cumaru tree belongs, contains neotropical species native Central and South American countries. They are used both in sale of timber seeds for extraction active compound coumarin, as a flavoring agent. This study evaluated phytochemical profile antioxidant activity extracts leaves, branches, fruits (residues seeds) Dipteryx punctata. plant material analysis was collected five seed-producing areas, Mojuí dos Campos, Pará, Brazil. were obtained via Soxhlet extractor using 92.8% distilled ethanol solvent operated till exhaustion (8 h). Chromatographic analyses performed by thin-layer chromatography (TLC) gas coupled mass spectrometry (GC-MS), followed determination phenolics flavonoids (TLC free radical scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH). highest extract yields from D. punctata fruit residues all with maximum values 26.1% 47.2%, respectively, Boa Fé (area 3). In evaluation TLC, presented classes terpenes, condensed hydrolysable tannins, flavonoids; coumarin (1,2-benzopyrone) identified only residue seed extracts. major constituents highlighted collection areas were: lupeol leaves (34.4% area 5), 4-O-methylmannose branches (85.5% 2 90.6% 5, respectively), (99.3% best results action residues, requiring concentration 117.6 µg.mL−1 160.4 reduce (DPPH) 50%. contributes reducing scarcity information on chemical compounds corroborate add value species, data reinforce importance reusing chemically rich but discarded environment.
