The Olive Tree (Olea europaea L.): A Source of Natural Antioxidants

The olive tree (Olea europaea L.) is a valuable source of natural antioxidants, particularly phenolic compounds such as hydroxytyrosol, tyrosol, oleuropein, flavonoids, and secoiridoids. These bioactive compounds, found in olive fruits, leaves, olive oil, and by-products, exhibit strong antioxidant properties and may help protect against oxidative stress. This book highlights the phytochemical composition, antioxidant activities, health benefits, and potential applications of olive-derived compounds, while emphasizing the sustainable valorization of olive products and by-products as sources of high-value natural antioxidants.
