"Antioxidant Activity of Three Species of Eugenia (Myrtaceae)". Extracts of Eugenia brasiliensis, E. beaurepaireana and E. umbelliflora were investigated for their antioxidant activity using DPPH, reducing potential and beta-carotene-linoleate system. Total phenolics and flavonoids contents were also determined. E. brasiliensis and E. beaurepaireana showed the highest antioxidant capacities in all methods used. These species exhibited too the highest phenolic contents. A significant relationship between antioxidant capacity and total phenolic content was found, indicating that phenolic compounds are the major contributors to the antioxidant properties of these plants.
