ANTIOXIDANT
- This study attributed antioxidant activity of olive leaves to its high oleuropein content. From: Le Tutour, B., & Guedon, D. (1992). Antioxidative activities of Olea europaea leaves and related phenolic compounds. Phytochemistry, 31(4), 1173-1178.
- Olive leaf and its phenolic constituents have antioxidant and antimicrobial activity. From: Lee, O. H., & Lee, B. Y. (2010). Antioxidant and antimicrobial activities of individual and combined phenolics in Olea europaea leaf extract. Bioresource technology, 101(10), 3751-3754.
- Oleuropein showed antioxidant activity. From: Visioli, F., Bellosta, S., & Galli, C. (1998). Oleuropein, the bitter principle of olives, enhances nitric oxide production by mouse macrophages. Life sciences, 62(6), 541-546.
ANTIMICROBIAL
- Opeuropein showed activity against microbes causing intestinal or respiratory tract infections in man. From: Bisignano, G., Tomaino, A., Cascio, R. L., Crisafi, G., Uccella, N., & Saija, A. (1999). On the in‐vitro antimicrobial activity of oleuropein and hydroxytyrosol. Journal of pharmacy and pharmacology, 51(8), 971-974.
ANTIDIABETIC
- The study shows that both oleuropein and oleanolic acid are involved in the anti-diabetic effect of olive leaves.
