Supercritical fluid extraction by using CO2 can be employed as an alternative to conventional methodsfor extracting functional compounds from vegetable leaves. Overall extractions curves of bioactive compounds from beetrootleaves were performed using scCO2 with ethanol as co-solvent. Yield,total phenoliccompounds and antioxidant activity were determined for each extract. The best results were obtained at35 ◦C/400 bar, with values of total phenolics 3370.8 g GAE/ g d.m. and antioxidant capacity by DPPH of1454.0 g TE/g d.m.
