“…Regarding the yield results, data similar to those obtained in this study for cumaru seeds were found when comparing conventional and supercritical ethanolic extractions of bioactives, resulting in a yield of 46.5%, using Soxhlet apparatus [23]. The high yield values obtained by the Soxhlet extraction method were attributed to solvent recirculation and solute-solvent interactions [24].…”

Dipteryx odorata and Dipteryx punctata are species native to the Amazonian, traded by extractivists to obtain coumarin. We aimed to analyze the presence of coumarin in the ethanolic extracts of leaves, branches and fruits of D. odorata and D. punctata and to evaluate the antimicrobial activity of these extracts against phytopathogenic fungi and bacteria of clinical interest. Chemical analyses were performed by thin layer chromatography (TLC) and by gas chromatography coupled to mass spectrometry (GC-MS). For the antifungal assays, the fungi used were Cercospora longissima, Colletotrichum gloeosporioides, two isolates of Fusarium spp. and Sclerotium rolfsii, and the antibacterial assay was performed using the minimum inhibitory concentration (MIC) test with Burkholderia cepacia, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus bacteria. In D. odorata seed extracts and in D. punctata husks, endocarps, and seeds, we identified 1,2-benzopyrone. D. odorata endocarp extracts and D. punctata seeds provided the greatest decrease in mycelial growth of the evaluated phytopathogens, showing promise as an alternative control. The husk and endocarp extracts of both species had a weak effect on E. coli. This research is the first to compare the different parts of species of the genus Dipteryx and to evaluate the use of husks and endocarps of D. punctata fruits to obtain coumarin. Chemical analyses used to quantify the compounds existing in the extracts, and tests with phytopathogens in vitro and in vivo are currently being carried out.

“…Extractions of leaves, branches, residues (separated into epicarp + mesocarp, and endocarp) and seeds of Dipteryx odorata and Dipteryx punctata have also been performed in a Soxhlet apparatus and, as in this study, the highest yields were obtained for extracts of fruit residues (epicarp + mesocarp) (44.1% and 54.2%) and for the seeds (48.9% and 44.5%) of the two species, respectively [10]. The yield of Dipteryx odorata seed extractions also resulted in values as high as 46.5% [34].…”

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