The present study aimed to assess chemical characterization of a methanolic extract of the Romina strawberry variety in terms of antioxidant capacity, polyphenols profile and chemical elements content. Additionally, potential toxicity, the effect on amyloid-{\ensuremath{\beta}} production and oxidative stress of the extract was in vivo evaluated in the experimental model Caenorhabditis elegans. Results revealed an important content in phenolic compounds (mainly ellagic acid and pelargonidin-3-glucoside) and minerals (K, Mg, P and Ca). The treatment with 100, 500 or 1000 {\ensuremath{\mu}}g/mL of strawberry extract did not show toxicity. On the contrary, the extract was able to delay amyloid {\ensuremath{\beta}}-protein induced paralysis, reduced amyloid-{\ensuremath{\beta}} aggregation and prevented oxidative stress. The potential molecular mechanisms present behind the observed results explored by RNAi technology revealed that DAF-16/FOXO and SKN-1/NRF2 signaling pathways were, at least partially, involved.}, url = {http://repositorio.uneatlantico.es/id/eprint/517/}, keywords = {Berries; Antioxidant; Anthocyanins; Minerals; RNAi; ROS} }
