Abstract

Total phenolic, flavonoid and antioxidant capacity of some commercially bagged herbal and fruit teas which belong to 3 different labels in Turkey’s markets were measured. % DPPH radical scavenging activity and reducing power were used for determining antioxidant activity. Total phenolic and flavonoid content of bagged teas were found as 6.46-83.87 (mg GAE/g) and 3.54 - 35.16 mg CE/g respectively. For all bagged herbal and fruit teas DPPH radical scavenging activity and reducing power were found as 63-95% and 0.267-0.456 respectively.

Piyasada Satılan Bazı Poşet Çayların Toplam Fenolik, Flavonoid Bileşen İçeriği ve Antioksidan Aktivitesinin Belirlenmesi

Abstract

Bu çalışmada marketlerde satılmakta olan üç farklı markaya ait poşet bitki ve meyve çaylarının toplam fenolik, toplam flavonoid bileşen içerikleri ve antioksidan kapasiteleri belirlenmiştir. Poşet çayların antioksidan aktivitelerinin tayininde, % DPPH (2,2-Difenil-1-pikrilhidrazil) radikal giderme aktivitesi ve indirgeme gücü metotları kullanılmıştır. Poşet çayların toplam fenolik ve toplam flavonoid değerleri sırasıyla 6.46-83.87 (mg GAE/g) ve 3.54 - 35.16 mg CE/g olarak belirlenmiştir. Analizi yapılan her üç markada % DPPH radikal giderme aktivitesi % 63-95 arasında değişkenlik göstermiştir. İndirgeyici güç değeri ise 0.267-0.456 arasında bulunmuştur.
