Popis: In this study, the ethanolic extract obtained from piquia pulp was assessed for genotoxicity and oxidative stress by employing the micronucleus test in bone marrow and peripheral blood cells in addition to comet, thiobarbituric-acid–reactive substances (TBARS), and reduced glutathione assays in the liver, kidney, and heart. Additionally, phytochemical analyses were performed to identify and quantify the chemical constituents of the piquia extract. Wistar rats were treated by gavage with an ethanolic extract from piquia pulp (75 mg/kg body weight) for 14 days, and 24 h prior to euthanasia, they received an injection of saline or doxorubicin (15 mg/kg body weight, intraperoneally). The results demonstrated that piquia extract at the tested dose was genotoxic but not mutagenic, and it increased the TBARS levels in the heart. Further studies are required to fully elucidate how the properties of ethanolic extract of piquia pulp can affect human health.
