Olea europaea Fruit Source & Identity
The botanical entity is Olea europaea L., the olive of the Oleaceae, an evergreen tree whose fleshy drupe changes from green to purple-black as it ripens. The part used is the fruit. Leaf, wood and pressed oil are not part of this olive fruit extract.
Olive products are easy to mix up. The leaf is rich in oleuropein and is sold as its own extract, while the fruit is the source of the secondary phenols that are measured as hydroxytyrosol after processing. The fruit also holds pectin, sugars and phenolic acids, named here only as families. A purchase form should state fruit and the Latin binomial.
