Total phenolic contents and antioxidant activities of "Ayvalık" and "memecik" olive leaves and olive fruits

Ayvalık ve memecik zeytin çeşitlerinin yaprağı ve meyvelerinin toplam fenolik madde miktarı ve antioksidan aktiviteleri

Abstract

In this study, the total phenolic content, DPPH• and ABTS•+ radical scavenging activities of olive leaves and fruits of "Ayvalik" and "Memecik" cultivars which were harvested from the Directorship of Bornova Olive Research Station during 2008/09 and 2009/10 harvest years were investigated. According to the cultivars, DPPH• and ABTS•+ radical scavenging activities of olive leaves and also the olive fruits total phenolic content, DPPH• and ABTS•+ radical scavenging activities were found statistically significant (P

Özet

Bu çalışmada 2008/09 ve 2009/10 hasat yıllarında Bornova Zeytincilik Araştırma İstasyonu Müdürlüğü bahçesinden toplanan Ayvalık ve Memecik zeytin yaprağı ve zeytin meyvelerinin toplam fenolik madde miktarı, DPPH• ve ABTS•+ radikal süpürücü aktiviteleri incelenmiştir. İstatistiksel olarak çeşitlere göre zeytin yaprağının DPPH• ve ABTS•+ radikal süpürücü aktiviteleri, zeytin meyvesinin toplam fenolik madde miktarı, DPPH• ve ABTS•+ radikal süpürücü aktiviteleri önemli bulunmuştur (P
