Publication date: Available online 12 October 2019Source: The Journal of Supercritical FluidsAuthor(s): Rosario Goyeneche, Karina Di Scala, Cristina L. Ramirez, María A. FanovichAbstractSupercritical fluid extraction by using CO2 can be employed as an alternative to conventional methods for extracting functional compounds from vegetable leaves. Overall extractions curves of bioactive compounds from beetroot leaves were performed using scCO2 with ethanol as co-solvent. Yield, total phenolic compounds and antioxidant activity were determined for each extract. The best results were obtained at 35 °C/400 bar, with values of total phenolics 3370.8 µg GAE/ g d.m. and antioxidant capacity by DPPH of 1454.0 µg TE/g d.m.Graphical abstract
