Aqueous extract of Baccharis trimera improves redox status and decreases the severity of alcoholic hepatotoxicity

ABSTRACT The metabolism of ethanol occurs mainly in the liver, promoting increase of reactive oxygen species and nitrogen, leading to redox imbalance. Therefore, antioxidants can be seen as an alternative to reestablish the oxidizing/reducing equilibrium. The aim of this study was to evaluate the antioxidant and hepatoprotective effect of aqueous extract of Baccharis trimera (Less.) DC., Asteraceae, in a model of hepatotoxicity induced by ethanol. The extract was characterized and in vitro tests were conducted in HepG2 cells. It was evaluated the cells viability exposed to aqueous extract for ...
