*4.2. Supercritical Fluid Extraction (SFE)*

The extraction process was carried out in a pilot plant described in detail in previous works [74,75]. All experiments were conducted in the 500 mL vessels loaded with 80 g of *A. mearnsii* dried flowers. The carbon dioxide mass flow was 800 g·h−<sup>1</sup> with a cosolvent flow rate of 0.5 mL·min<sup>−</sup>1.
