Details
Maximum lifespan of flies supplemented with 10 mg/ml AP (apple polyphenols) was approximately 16% longer than controls after exposure to paraquat stress.

Environment Interventions

Type Body
Dietary enhancement Apple polyphenols (AP) at various concentrations.
Paraquat After 2 h of starvation, were transferred into vials containing a filter paper that was saturated with 1 mL of 20 mM paraquat in a 6% glucose solution. After 24 h, flies were moved to new vials containing only a water-saturated filter paper for 2 h before they were transferred back into vials containing respective diets.
