Supercritical CO2 extraction of açaí (Euterpe oleracea) berry oil: Global yield, fatty acids, allelopathic activities, and determination of phenolic and anthocyanins total compounds in the residual pulp

- The highest global yield was obtained in the experimental condition of 70 °C/490 bar.
- The fatty acids analysis of açaí extracts shows a low saturated/unsaturated ratio.
- The extracts had phytotoxic effects for the species M. pudica.
- Radicle and hypocotyl growth were lower for the species M. pudica than S. obtusifolia.
- The residual pulp after extraction were rich in phenolic compounds and anthocyanins.
