Product Description
Olive leaf extract is sold against four markers that do not substitute: total polyphenols (about 10–70%), oleuropein (about 10–80%), hydroxytyrosol (about 5–20%), and oleanolic acid (about 60–98%).
Oleuropein is the bitter leaf secoiridoid used in immune-style capsules. Hydroxytyrosol is the smaller phenol also found in olive oil and fruit. Oleanolic acid is a triterpene used in a different dose.
When buying, circle one marker. “Olive extract 40%” is not a spec.

Applications
Hydroxytyrosol
A different marker, often for antioxidant topicals. Do not ship oleuropein against it.
Oleanolic Acid
A triterpene grade. It will not pass an oleuropein HPLC.
Match the Marker to the Capsule
Oleuropein, hydroxytyrosol and oleanolic acid are three different fills.
Bitter Leaf
Oleuropein grades are bitter. Do not brief them as olive oil.
Not Olive Oil
Oil phenols are a different product. This code is the leaf.
Leaf Infusions
A tea will not deliver an 80% oleuropein assay. The extract dose is the label dose.
