G1—plant material of a coarse size; G2—plant material of a very small size; EtOH—ethanol; MeOH—methanol; MAE—microwave-assisted extraction. The results are the mean of the three determinations carried out ± the standard deviation. Values are presented as means ± SD, n = 3 per treatment group. Data in the Extraction yield (%) column without a common superscript letter differ (p < 0.05), as analyzed by one-way ANOVA and the TUKEY test, for each plant species.
