ABSTRACT
Essential oils obtained from Brazilian native species exhibit a wide range of chemical compositions and remarkable biological activities. In this study, the chemical components of a variety of oils were analyzed, and their associated target enzyme activity evaluated using the enzymes α-glucosidase and acetylcholinesterase as research targets. The essential oil from the species Marlierea eugeniopsoides was collected using the hydrodistillation method, and the chemical composition determined via gas chromatography coupled to a mass spectrometer. Summer-season-derived oils had the greatest activity, accounting for 94.3%. In the inhibition of α-glucosidase activity, the autumn- and spring-derived oils reached extremely satisfactory results with 100% and 96.61% efficacy, respectively. Spring-derived oils had the highest concentration of monoterpene compounds, consisting mainly of α-pinene (54.85%) and β-pinene (32.44%).
