Effects of the PEEs in cell viability of AGS cells challenged with H₂O₂ (1.5 mM) + Cu²⁺ (410 μM). (a) Cytoprotective effects of the PEEs from Rubus geoides (Las Raices and Lago Blanco) in the coincubation model. (b) Cytoprotective effects of the PEEs from R. geoides (Las Raices and Lago Blanco) in the preincubation model. (c) Cytoprotective effects of the PEEs from Fragaria chiloensis and Ribes magellanicum in the coincubation model. (d) Cytoprotective effects of the PEEs from F. chiloensis and R. magellanicum in the preincubation model.
