The focus on diversity in the Amazon forest is related to fruits and oilseeds that have diverse nutritional and functional values in their composition and contribute to human health. Therefore, this research aims to study the functional constituents of lipid extracts obtained from peach palm (Bactris gasipaes Kunt) of the red variety obtained by green extraction with the assistance of ultrasound probe. The methodology followed established and internationally accepted standards, with comparative analyses of the quality of the oils, fatty acid profile by gas chromatography (GC), cardiovascular functionality indices and chemical profile by Fourier transform infrared spectroscopy (FTIR). The results obtained in this research demonstrate a yield equal to 9.81% on a dry basis, in addition to demonstrating high quality of the lipid extracts, presenting an acidity index equal to 1.85 mg KOH/g, a peroxide index equal to 2.75 mE/kg in of the limits established by Brazilian legislation. The fatty acid profile shows a high concentration of omega-9 (59.03%), an index of the ratio of hypocholesterolemic and hypercholesterolemic fatty acids equal to 2.45 and a predominance of unsaturated fatty acids, highlighting omega 9 (60.2 %), 6 (3.90%) and 3 (1.05%). FTIR spectra confirm a high presence of unsaturated fatty acids. Therefore, the data demonstrate benefits of extracting peach palm oil assisted by ultrasound, as it provides maintenance of nutritional and functional quality, keeping the constituents linked to the anti-inflammatory processes.
