This study investigated the supercritical CO2 extraction of oils from capuchin (Tropaeolum majus) seeds (4.34% moisture content) and leaves (5.26% moisture content) and analyzed the effects of varying temperature and pressure conditions. The extraction yields were 3% for the seeds and 2% for the leaves. The seed extracts were rich in oleic, linoleic, and palmitic fatty acids, whereas the leaf extracts contained a high concentration of octacosanol (73.37%). Kinetic analysis revealed distinct mass transfer mechanisms during extraction, and the Sovová model effectively described the extraction kinetics, showing good agreement with experimental data (ADD% < 4%). An analysis of variance (ANOVA) demonstrated the impact of temperature and pressure on the yields, with temperature being the most influential factor. The experimental conditions ranged from 22 to 28 MPa and from 313.15 to 333.15 K. This study contributes to the understanding of capuchin oil extraction and its potential applications in various fields, owing to the presence of bioactive compounds. [ABSTRACT FROM AUTHOR]

This work investigated the effect of different extracting agents on the extraction of phenolic compounds from agro-industrial residues of seriguela. Additionally, the phenolic compounds partitioning was studied using aqueous two-phase systems based on the extracting agents. The effect of the type of extracting agent such as water, organic solvent (1,3-dioxolane, acetone, 1,4-dioxane, and acetonitrile), and different ionic liquids (ILs) was evaluated. Afterward, solvent concentration, solid-liquid ratio, and time were analyzed in the extraction process. The solvent polarity played an important role in the extraction; thus 1,3-dioxolane (20 wt%), solid-liquid ratio 1:10 for 45 min was the best condition presented for organic solvents (1437.00 ± 0.01 mg L-1). On the other hand, [C2mim][CH3SO3] (20%), liquid-solid ratio 1:10 for 10 min was the best condition using IL (1842.56 ± 42.43 mg L-1). The mixture of water (60 wt%) + 1.3 dioxolane (20 wt%) + [C2mim][CH3SO3] (20 wt%) increased the concentration of phenolic compounds to 1894.22 ± 90.51 mg L-1. The phase separation was performed with the addition of organic solvent, reaching the mixture composition of 1,3-dioxolane (40 wt%) + [C2mim] [CH3SO3] (10 wt%) + water (50 wt%) at 25 °C, allowing the recovery of the phenolic compounds (98.63 ± 0.15%) to the bottom phase (IL-rich phase) and a partition coefficient of 0.0092 ± 0.0002.
