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

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