Abstract:

 In the present study, total antioxidant activity TAC, phenolic compound amounts TPC and reducing power RP of hazelnut leaves collected from Giresun were investigated. Antioxidant levels were determined in the water extracts of hazelnut leaves by using methods according to the appropriate literature. In the results obtained from water extracts at three different doses 1, 2.5 and 5 mgkg, it was determined that the total antioxidant capacity was high depending on the dose and phenolic content. The high antioxidant capacity of hazelnuts produced in humid regions in our country also depends on the phenolic substance content it has.

 Bu çalışmada, Giresundan toplanan fındık yapraklarının toplam antioksidan aktivitesi TAC, fenolik bileşik miktarları TPC ve indirgeme gücü RP incelenmiştir. Fındık yapraklarının su ekstraktlarında antioksidan seviyeleri literatüre uygun yöntemler kullanılarak belirlenmiştir. Su ekstraktlarından üç farklı dozda 1, 2.5 ve 5 mgkg elde edilen sonuçlarda doza ve fenolik içeriğe bağlı olarak toplam antioksidan kapasitenin yüksek olduğu belirlenmiştir. Ülkemizde nemli bölgelerde üretilen fındığın antioksidan kapasitesinin yüksek olması sahip olduğu fenolik madde içeriğine de bağlıdır. Sonuçlardan da görülebileceği gibi fenolik içerik de doza bağlı olarak artış göstermiştir.
