- Abstract
Objective: Evaluation of antioxidant activity has been an important issue considering its importance to human health. Recent studies show that the use of plants in the form of juices or teas as sources of natural antioxidants which have a low risk can be used as an aid to the treatment of various diseases. Materials and methods: In this context, evaluated the antioxidant potential in vitro , extracts of Eugenia uniflora and Psidium sobraleanum and quantifies phenols and flavonoids present in the extracts. Results: According to the results, showed a better antioxidant activity for the extract of Eugenia uniflora for testing TBARS with phospholipid, egg extracts reduced basal levels in the process of lipid peroxidation, and when induced by Fe2 + extract Psidium sobraleanum proved to be more efficient. Conclusions: Therefore, through these tests can be seen that the extracts of the leaves of the species, Eugenia uniflora and Psidium sobraleanum, exhibit antioxidant activity, directly related phenolic substances produced from its secondary metabolism.
