- Natural Occurrence
Hydroxytyrosol in oil is found free, in acetate form or as a part of more complex compounds like oleacein, oleuropein, and verbascoside. Oleuropein is responsible for the bitter taste of olives and decreases as the fruit ripens turning into unglycosylated form, oleuropein aglycone by enzymatic hydrolysis, and finally converted into hydroxytyrosol, being this one an indicator of maturation of the olives.
- Physiological Activity
Hydroxytyrosol is one of the natural antioxidants with highest physiological activity.
Hydroxytyrosol and antioxidant and scavenging of free radicals
- Euronutra hydroxytyrosol antioxidant was evaluated by using the stable free radical DPPH.
- The radical scavenging ability of single polyphenols present in the extract (verbascoside, hydroxytyrosol and caffeic acid) was compared to ascorbic acid and oleuropein. Verbascoside turned out to be five times more active compared to oleuropein.
- Euronutra hydroxytyrosol polyphenols were tested for their scavenging activity on superoxide anion, an activated oxygen species. This model mimics closely the in vivo situation, since the formation of the superoxide anion takes place in tissues and cells, and is, for example, triggered by UV exposure of the skin.
- These data are related to an independent study showing that verbascoside outperforms caffeic acid or hydroxytyrosol, both individually and in equimolar mixtures, in antioxidant assays.
