Abstract

Sonchus (Asteraceae) cinsi Türkiye’de yedi takson ile temsil edilmekte ve Anadolu’da tıbbi amaçla geleneksel olarak kullanılmaktadır. Bu çalışmada, Sonchus asper subsp. glaucescens’in farklı kısımlarından elde edilen farklı özütlerin (su ve etil alkol) fitokimyasal içeriği ve antioksidan etkileri farklı test sistemleri kullanılarak belirlendi. Ayrıca, toplam fenolik ve flavonoit miktarları da hesaplandı. Genel olarak, yaprak ve çiçek özütlerinin yüksek miktardaki antioksidan komponentler ile önemli düzeyde antioksidan aktivite sergilediği belirlendi. Özütlerin toplam fenolik içeriği ile antioksidan aktiviteleri arasında korelasyonun önemli olduğu tespit edildi. S. asper subsp. glaucescens bitkisinin gıda ve terapötik uygulamalar için doğal antioksidanların bir kaynağı olabileceği belirlendi.

Abstract

The genus Sonchus (Asteraceae) is represented in Turkey by seven taxa, which are traditionally used for medicinal purposes in Anatolia. In this study, the phytochemical content and antioxidant effect of different solvent extracts (water and ethyl alcohol) from different parts of Sonchus asper subsp. glaucescens were tested using different chemical assays for antioxidant activity. The total phenolics and flavonoids were also calculated. Generally, both extracts from leaves and flowers showed significantly higher antioxidant activity with high antioxidant components. Total phenolic content of the extracts were significantly correlated with antioxidant potentials. On the basis of the results obtained, S. asper subsp. glaucescens should be regarded as a valuable source of natural antioxidants for food and theurapeutic applications.
