Chagas Disease and Leishmaniasis are neglected parasitic diseases that constitute a major public health problem. In the search for new therapeutic alternatives for such pathologies, the essential oil of the leaves of Psidium brownianum Mart ex DC was investigated egarding its chemical composition, antiparasitic, and cytotoxic effects. The chemical composition of the oil was analyzed by gas chromatography coupled to mass spectrometry (GC/MS), showing two major constituents: Isogermafurene (52.93%) and Germacrone (16.02%). In antiparasitic activity, the oil was tested against the epimastigote forms of Trypanosoma cruzi, revealing 57.05% inhibition at the highest tested concentration (1000 μg/mL). In regard to antiparasitic activity against promastigote forms of Leishmania braziliensis and ishmania infantum, it obtained 92.61% and 84.16% inhibition, respectively, at the highest concentrations (1000 μg/mL). As for the cytotoxic effects, it showed high cytotoxicity, with IC50 = 328.9 μg/mL. The inhibitory concentration (IC50) obtained the best result for the promastigote forms of L. braziliensis (IC50 = 37.53 μg/mL), as well as the selectivity index (SI = 8.76). Such results generate perspectives for new research and may contribute to more effective drug discoveries. |

Background: Açaí (Euterpe oleracea), a superfruit consumed worldwide, is a Brazilian Amazon native fruit, with high nutritive value due to its high content of lipids, proteins, and fibers, besides bioactive compounds, such as anthocyanins, carotenoids and phenolic compounds in its composition associated with biological action beneficial to health. The increased consumption of this fruit has stimulated breeding programs in the search of plants and fruits with higher productivity and bioactive compounds, generating information for the development of new cultivars with improved attributes. This work aimed to study six different genotypes of açaí, developed by the breeding program, evaluating their physicochemical characteristics and proximate composition, bioactive compounds and antioxidant activity. Methods: The genotypes were analyzed for titratable acidity, pH, total soluble solids and proximate composition, such as moisture, protein, lipids, total fiber, carbohydrates and ashes contents. A spectrophotometric method using Folin-Ciocalteau reagent performed the phenolic compounds analysis and HPLC evaluated carotenoids and anthocyanins extracted exhaustively. The ABTS assay evaluated the antioxidant activity. Results: The L06P13 and L09P09 genotype presented higher content of total fiber, carbohydrates, and ashes when compared to the commercial sample used as a standard. Furthermore, L22P13 genotype showed the highest content of total anthocyanins (6745.81 mg/100g), total carotenoids (118 ?g/g) and antioxidant activity (674.83 ?M Trolox/g)) when compared to commercial sample. Conclusion: The results revealed promising açaí genotypes and support the importance of advances in the area of functional foods and breeding programs.
