Abstract

Olive (Olea europea L.) trees are widely grown in Mediterranean region and leaves are used as a traditional medicine. Oleuropein is the main active compound for the olive leaves. Olive leaves have potentially beneficial effects on certain health conditions, including antimicrobial and antioxidant and other biological activities. These beneficial effects may be due to the antioxidant components of olive leaves, especially oleuropein. Oleuropein containing extracts are used in many supplements for different pharmacological activities. In this study, oleuropein amounts of olive leaves from seven different localities of North Cyprus were investigated by HPLC. Olive leaves were extracted by methanol according to European Pharmacopoeia’s method. Oleuropein amounts of the extracts were calculated by reversed phase HPLC with PDA. Buyukkonuk and Guzelyurt samples contain the highest amount of oleuropein, followed by Tatlisu, Dipkarpaz, Lapta, Zeytinlik and Lefke.
