Additional recommended knowledge
Hydroxytyrosol is found in olive oil in the form of its elenolic acid ester oleuropein and, especially after degradation, in its plain form. Both compounds, along with oleocanthal, are responsible for the bitter taste of extra virgin olive oil. The wastewaters generated during olive processing contain a high levels hydroxytyrosol, most of which can be recovered to produce hydroxytyrosol extracts.
Studies by Visioli et al (2000) showed that a low dose of hydroxytyrosol reduces the consequences of sidestream smoke-induced oxidative stress in rats.
