Secoiridoid polyphenols (oleuropein)

Olive leaves contain several secoiridoids, including oleuropein (the greater part) but also oleosid, oleurosid… The extract from olive leaves is traditionally used for its hypotensive properties. Olive-based polyphenols (hydroxytyrosol and its derivatives, such as oleuropein) were recently recognized by the EFSA (European Food Safety Authority) for their health benefits in preventing LDL, low-density lipoprotein oxidation. Many reports also recognized the anti-oxidant, anti-microbial and anti-inflammatory properties of oleuropein.
