Extraction efficiency of 7 deep eutectic solvents (DESs) and three conventional solvents: (a) total flavonoid content (TFC); (b) total phenolic acid content (TPC); (c) radical scavenging capacity determined by DPPH● assays; and (d) radical scavenging capacity determined by ABTS●+ assays. Extraction efficiencies that differed significantly from those of DES-2 are indicated with an asterisk * (p < 0.05). Data were analyzed with ANOVA followed by post hoc Tukey’s test.
