What's Oleuropein？
Oleuropein is a chemical compound found in olive leaf from the olive tree (and leaves of privet) together with other closely related compounds such as 10 hydroxyoleuropein, ligstroside, and 10-hydroxyligstroside. 
All these compounds are tyrosol esters of elenolic acid that are further hydroxylated and glycosylated. 
Oleuropein is a glycosylated seco-iridoid, a type of phenolic bitter compound found in green olive skin, flesh, seeds, and leaves, and argan oil.The term oleuropein is derived from the botanical name of the olive tree, Olea europaea. Because of its bitter taste, oleuropein must be completely removed or decomposed to make olives edible. During processing of bitter and inedible green olives for consumption as table olives, oleuropein is removed from olives via a number of methods, including by immersion in lye.
