Özet
Oxidative stress can cause several degenerative conditions, including inflammation, cardiovascular diseases, and cancer. Organisms have inherent mechanisms to reduce oxidative stress, but it is not entirely effective. Thus, they can benefit from additional antioxidants. Many fruits, vegetables, and plant leaves have antioxidant properties. Olive leaves are particularly interesting because they have been used in traditional treatments throughout the Mediterranean [ 1 ], and their health benefits have been supported by scientific studies [ 2 ].On the other hand, different olive leaves cultivars showed different antioxidant activity [ 3 ]. This presentation will cover the antioxidant capacity of two different Olea europaea Domat olives cultivars and Sari Yaprak olive leaves collected from Izmir, Turkey. Domat olive leaves showed higher antioxidant capacity when compared with 21 other olive cultivars [ 3 ]. The Sari Yaprak olive cultivar is exclusively grown in Turgutlu and Manisa, Turkey. In addition, how the antioxidant capacity of sari yaprak olive leaves was affected by geographical features was tested. Different cultivars of olive leaves were extracted with 80% methanol. Their antioxidant capacities were compared with DPPH radical scavenging activity, CUPRAC (cupric reducing antioxidant capacity), and TOAC (total antioxidant capacity) assays. Their phytochemical properties were compared with total phenolic content and total flavonoid content. Sari Yaprak olive leaves showed higher total flavonoid content than Domat olive leaves, whilst Domat olive leaves had higher antioxidant activity on CUPRAC than Sari Yaprak olive leaves. Furthermore, environmental conditions such as altitude, climate, and light affected the total phytochemical assays and antioxidant activities of Sari Yaprak olive leaves.
