the extracts obtained with CO2 + co-solvent present similar bands; in other words, it presented basically the same composition. Moreover, although it has not been observed the presence of compounds used as standard in some SFE extracts, as quercetin, higher number of functional compounds (essential oils, flavonoids, carotenoids, anti-oxidant compounds) were detected in the extracts obtained with supercritical CO2 + co-solvent than that extracts obtained with only supercritical CO2. Then, with these results, the optimization of the SFE extraction process using a factorial experimental design was carried out using ethanol (5%) as a co-solvent. Ethanol was chosen over isopropyl alcohol as it costs less and is easier to use.
