1Values are mean ± standard deviation (SD) of three repetitions. One-way ANOVA, with post hoc analysis (Tukey test), is indicated by a different letter for each response variable (per extract and reaction time). Means followed by a different lowercase letter in the same column indicate significant differences (p < 0.05) between the extracts tested. Values followed by a different uppercase letter in the same row indicate significant differences (p < 0.05) between the reaction time tested for each extract.
