Phenolic extract from olive mill wastewater sustains mitochondrial bioenergetics upon oxidative insult.

In the last few years, many efforts have been devoted to the recovery and valorization of olive oil by-products because of their potentially high biological value. The olive mill wastewater (OMWW), a dark-green brown colored liquid that mainly consists of fruit vegetation water, is particularly exploited in this regard for its great content in phenolic compounds with strong antioxidant properties. In our previous work, we produced different OMWW fractions enriched in hydroxytyrosol- and hydroxytyrosol/oleuropein (i.
