Oleuropein is a chemical compound found in olive leaf from the olive tree (and leaves of privet) together with other closely related compounds such as 10-hydroxyoleuropein, ligstroside, and 10-hydroxyligstroside. All these compounds are tyrosol esters of elenolic acid that are further hydroxylated and glycosylated. Oleuropein and its metabolite hydroxytyrosol have powerful antioxidant activity both in vivo and in vitro and give extra-virgin olive oil its bitter, pungent taste. Oleuropein preparations have been claimed to strengthen the immune system.

Hydroxytyrosol (3, 4-dihydroxyphenylethanol; DOPET) is a phytochemical with antioxidant properties. After gallic acid, hydroxytyrosol is believed to be one of the most powerful antioxidants. Its oxygen radical absorbance capacity(ORAC) is 40,000 umolTE/g, which is ten times higher than that of green tea, four times higher than that of VC, and two times higher than that of CoQ10.
In nature, 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 olives, leaves and olive pulp contain small amounts of hydroxytyrosol, most of which can be recovered to produce hydroxytyrosol extracts.
