1. Introduction

Oleuropein, also known as olive bitter, is a natural plant extract, mainly from olive leaves. The olive tree, Olea europaea, is an evergreen tree or shrub of the Mediterranean, Asia and Africa. The leaves have been medicinal at different times and locations. Natural olive leaf and olive leaf extract (OLE) are now marketed as anti-aging, immune stimulators and antibiotics.

Oleuropein, the active ingredient of olive leaf extract, is resistant to insects and bacteria. Olive leaf extract may be beneficial because of its polyphenolic fraction, oleuropein, which is the same as the polyphenolic component of red wine. Resveratrol and oleuropein have some important antioxidant effects for users - reducing LDL oxidation is one of the keys.
