Supercritical CO2 extraction of α-/β-amyrin from uvaia (Eugenia pyriformis Cambess.): Effects of pressure and co-solvent addition

The obtaining of α-/β-amyrin from Eugenia pyriformis leaves is a subject with few studies that needs to be explored further in order to extend the understanding about processes to recover these compounds. Thus, the objective of this study was to evaluate the effects of pressure and co-solvent addition in the supercritical CO2 extraction regarding the global extraction yield, α-/β-amyrin purity and yield, and antioxidant activity.
