Biophenols, Oleuropein & Hydroxytyrosol

From recent studies Extra Virgin Olive Oil typically has more than 20 different biophenols . The prevalent classes of hydrophilic phenols found in EVOO are phenolic alcohols and acids (i.e. Hydroxytyrosol and vanillic acid), flavonoids (i.e. luteonin), lignans (i.e. pinoresinol) and secoiridoids. Among these substances the last two classes include the most concentrate phenols of EVOO. Secoiridoids, like aglycone derivatives of oleuropein, demethyloleuropein and ligstroside, are present in olive fruit as most abundant EVOO phenolic antioxidants. Several important biological properties (antioxidant, anti-inflammatory, chemopreventive and anti-cancer) along with the characteristic pungent and bitter tasty properties have been attributed to EVOO phenols.
