Abstract

Bu çalışmada, Hatay’da farklı bölgelerde yetiştirilen
Halhalı türü zeytin (Olea europaea)ağaçlarının
yapraklarının metanol ekstraktlarının antioksidan aktiviteleri belirlenmiştir.
Toplam fenolik madde miktarları Folin-Ciocaltaeu yöntemi ile tayin edilmiştir.
Antioksidan özelliklerini belirlemek için kullanılan diğer yöntemler DPPH  radikal süpürme yöntemi, FRAP  indirgeme gücü metodu  ve β-karoten-linoleik asit emülsiyon
yöntemidir. Sonuçlar standart antioksidanlar ile (BHA, BHT) kıyaslanmıştır.
İncelenen tüm bölgelerin zeytin yapraklarının antioksidan aktiviteye sahip
olduğu belirlenmiştir.

Determination of Antioxidant Properties of Olive Leaves Grown in Different Regions in Hatay

Abstract

In this study; antioxidant activities of metanol extracts of olive leaf (Olea eueopaea) which is grown in different parts
of Hatay were determined. Total phenolic contents were determined by the Folin-Ciocaltaeu method. The other
methods used to determine the antioxidant characteristics were 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical
scavenging method, ferric ion reducing power (FRAP) and β-carotene-linoleic acid emulsion method. The results were
compared with the standard antioxidants butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). It was
determined that olive leaves in all regions examined had antioxidant activity.

Keywords

Olive leaf, total phenolic content, antioxidant activity, DPPH
