Determination of process parameters and bioactive properties of the murici pulp (Byrsonima crassifolia) extracts obtained by supercritical extraction.

Graphical abstract Highlights • Increase of 50% in the Q C O 2 reduced in 33.3% the extraction dynamic period. • Lutein and antioxidant capacity was found in both extracts. • Extract was antihypercholesterolemic, antiatherosclerogenic, and antithrombogenic. • CO 2 +EtOH-SFE of defatted dried pulp was selective for phenolic compounds. • Linear correlation phenolic compounds×antioxidant capacity was positive. Abstract The obtaining of muruci extracts (Byrsonima crassifolia) was performed by CO 2 -SFE and CO 2 +EtOH-SFE, which were conducted at 323.15 K–343.15 K, and at 15 MPa to 49 MPa. The increase of 50% in the solvent flow rates, and the reduction of 33% in the dynamic period increased the yields. For the CO 2 -SFE, the highest values of global yield (9.12%), lutein (207.18 μg/g), and antioxidants (33.91 μmol TE/g) were obtained at 333.15 K. In the CO 2 +EtOH-SFE of the defatted freeze dried murici pulp, the highest values of lutein (209.73 μg/g), phenolics (43.69 mg GAE/g), and antioxidants (138.85 μmol TE/g) were obtained at 940 kg/m3, with a strong positive phenolics/antioxidants correlation. The functional quality suggests hypercholesterolemic, antiatherosclerosis and antithrombogenic effects. [ABSTRACT FROM AUTHOR]
