Oleuropein is a glycosylated seco-iridoid, a type of phenolic bitter compound found in green olives, olive leaves, and argan oil.[1][2][3] During processing of inedible green olives for human consumption as table olives, oleuropein is removed from olives by immersion in lye.[4]

Basic research[edit]

In preliminary laboratory research, oleuropein had activity as an agonist of the G-protein estrogen receptor.[5] Other basic research is examining whether oleuropein and other olive polyphenols have pharmacological properties and potential anti-disease activity,[6] none of which is proved to exist in humans as of 2017.[2]
