Identification of Coumarins and Antimicrobial Potential of Ethanolic Extracts of and .

and 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 and 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 , , two isolates of spp. and , and the antibacterial assay was performed using the minimum inhibitory concentration (MIC) test with , , and bacteria. In seed extracts and in husks, endocarps, and seeds, we identified 1,2-benzopyrone. endocarp extracts and 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 . This research is the first to compare the different parts of species of the genus and to evaluate the use of husks and endocarps of 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.
