The present study describes the in vitro antioxidant activity of methanol extracts of 34 plant species collected in the Colombian coffee-growing eco-region belonging to Euphorbiaceae, Piperaceae and Solanaceae families. The antioxidant properties of extracts were evaluated by determining radical scavenging power measured with a DPPH assay. The methanolic extracts of Hyeronimia antioquiensis, Mabea montana, and Alchornea grandis species (Euphorbiaceae), presents EC50 values equal to 0.686, 12.35, and 13.01 µg/mL, respectively, showing high antioxidant potential.
