Essential Oils and Antimicrobial Activity

Oenocarpus distichus is a native palm from Brazilian Amazon biomes, its fruits are sources of bioactive compounds and, mainly, vegetable oil rich in unsaturated fatty acids. In this study, the supercritical CO2 (ScCO2) extraction was applied to obtain the bacaba-de-leque pulp oil, evaluating its composition and the bioactive compounds contents present in the pulp before and after the extraction. The maximum oil yields were reached at 50 °C/350 bar (45.23%) and 60 °C/270 bar (45.90%). The oleic, palmitic, and linoleic acids, as well as the predicted triglycerides OLiO, PLiO, OOO, POP, and POO were predominant in the oil composition, independent of the extraction conditions, and presented excellent functional quality. There was an increase in phenolic compounds, total anthocyanins contents, and antioxidant capacity of the bacaba-de-leque pulp extracts after the ScCO2 extraction, showing possible applications for nutraceutical purposes.
