1: Yield, TPC, and TEAC values, expressed per mass unit of unextracted D. fruticosa leaves; 2: SFE-CO2 performed at 45 MPa, 60 °C, 360 min; 3: Soxhlet extraction performed at atmospheric pressure (0.1 Mpa), 68 °C, 360 min; *: Yieldsolid residue = 100−Yieldnon-polar extract, g/100 g DW. He: hexane; SFE-CO2: supercritical carbon dioxide extraction; TEAC: Trolox equivalent antioxidant capacity; TPC: total phenolic content. Different superscript letters within the same column indicate significant differences (one-way ANOVA and Tukey’s test. p < 0.05).
