  1. Values are expressed as mean ± standard deviation (n = 6)
  2. Different letters (a, b, c) in the same row indicate significant differences between concentrations of the same sample extracted by different methodologies (p < 0.05), according to Tukey’s HSD test
  3. Different superscript numbers (1,2,3) in the same species at the same concentration represent significant differences (p < 0.05) between the extraction technique employed (p < 0.05), according to Tukey’s HSD test. Subcritical water extraction carried out with a solid to solvent ratio of 1:30 (w/v), 1 h at 160 °C with (1) 20 bar N2, (2) 20 bar N2 with 0.05 M HCl, (3) 20 bar CO2
