R.  aSupercritical CO2 extraction of açaí (Euterpe oleracea) berry oilbGlobal yield, fatty acids, allelopathic activities, and determination of phenolic and anthocyanins total compounds in the residual pulp.h[electronic resource]  c2016  aAçaí (Euterpe oleracea) is a very popular fruit in the Brazilian Amazon consumed as a nourishing and tasty food. Studies suggest that E. oleracea has therapeutic effects on problems like cancer, hypocholesterolemia, fatty liver, malaria, and neurodegeneration. The supercritical fluid extractions were performed with supercritical CO2 at densities of 700, 800, and 900 kg/m3 while varying three and eight nominal values of temperature and pressure, respectively. The extracts were analyzed for total fatty acid contents and allelopathic effects. In addition, lyophilized açaí berry pulp was analyzed before and after supercritical CO2 extraction to determine phenolic compounds and anthocyanin contents. The açaí extract isotherm of 70 °C showed the highest yields at the pressures applied while the isotherm of 60 °C showed the lowest yields. Thus, the fatty acids profile analysis of açaí extract indicates a low saturated/unsaturated ratio and the amount of MUFA is greater than of PUFA. The extracts had phytotoxic effect for the species Mimosa pudica and some extracts had stimulatory effects on Senna obtusifolia germination. Radicle and hypocotyl growths were shorter for the species M. pudica than for S. obtusifolia. The phenolic compounds and anthocyanin contents in the lyophilized açaí berry pulp after CO2-SE shows potential applications for nutraceutical purposes.  aAçaí  aÁcido Graxo  aAlelopatia  aÓleo  aExtração de fluido1 aOLIVEIRA, M.
