Butiá fruit extract (Butia eriospatha) protects against oxidative damage and increases lifespan on Caenorhabditis elegans.

Butiá (Butia eriospatha) is a fruit of a palm tree belonging to the family Arecaceae, native to South America. The aim of this study was to evaluate the antioxidant potential of butiá extract using Caenorhabditis elegans as animal model. Initially, we performed survival experiments, reproduction, resistance to oxidative stress (post or pre-treatment with paraquat or hydrogen peroxide), longevity, superoxide dismutase, and catalase GFP reporters' expression.
