Several animal diseases involve an increase on reactive oxygen species (ROS) production, which could cause biological effects as aggravating of pre-existing diseases or cell damage in infectious diseases. In addition, in vitro embryo production (IVP) induces excessive ROS production, which affects blastocyst quality. Therefore, the use of antioxidants represents an alternative to overcome oxidative stress damage both, in infectious diseases and in improving animal reproduction procedures. Brazil is a country of interest to ethnopharmacology, especially the ecological domain Cerrado, which represents a source of biological diversity. The purpose of this study is to evaluate crude extracts of plants from Cerrado used in traditional medicine, for the presence of phenolic compounds as well as its antioxidant activity, antibacterial and effect on apoptosis in IVP.
