Results represent the mean±standard deviation of three independent replicates.
Values with different lowercase letters within the same column indicate significant differences (P<0.05) between solvents. Values with different capital letters within the same row indicate significant differences (P<0.05) between extraction methods.
EtOH, ethanol; CH2Cl2, dichloromethane; EtOAc, ethyl acetate; EtOH/H2O, ethanol-water; ND, not tested due to very low values, which could not be measured accurately.
