Values are presented as ; each extract was tested in triplicate. For each plant, extracts were compared regarding the organic solvent (two-way ANOVA followed by Tukey’s test) and zileuton (two-way ANOVA followed by Dunnett’s test). Within each column, values bearing different letters ^{(a, b, c, d, e, f, g, h, i, j, and k)} are considered highly statistically significant at . All organic extracts were statistically significantly () different from zileuton.
