# Amount (%) of Lippia alba extract required to scavenge 50% of the 1,1-diphenyl 2-picrylhydrazyl radical. § µL of extract required to reduce 50% of the adrenochrome formation. Different letters correspond to values significantly different using an analysis of variance (ANOVA) and Tukey’s post hoc test for p ≤ 0.05 for each assay.
