Şebinkarahisar (Giresun) Yöresinde Yetiştirilen ‘‘Alişar’’ Armut Çeşidinin Biyoaktif Profili

Abstract

With a history of at least three centuries, ''Alişar'' is a local pear (Pyrus communis L.) variety that is widely grown in the district of Şebinkarahisar in Giresun province. In recent years, researches on the bioactive compounds of fruits that are valuable for human health has gained importance. This research was performed to determine fruit bioactive profiles of 27 clones belonging to this variety. The total phenolic content, antioxidant activity and total flavonoid content in the fruits of the clones were investigated as bioactive properties. Total phenolic contents of the clones were found between 72.61-147.38 mg 100 g -1 . In the FRAP and DPPH assays, the antioxidant activity was determined between 2.61-4.27 mmol kg -1 and 0.18-0.76 mmol kg -1 . The total flavonoid content was detected between 3.05-18.01 mg 100 g -1 . According to the FRAP assay, there was a high positive correlation (r = 0.679 ***) between total phenolic and antioxidant activity, while total phenolics showed a moderate relationship with antioxidant activity (R 2 = 0.461). The findings revealed that Alişar pear clones showed variation in fruit bioactive components, and also some clones were rich in bioactive contents. A-19 in total phenolic content, A-23 in antioxidant activity and A-18 in total flavonoid content were evaluated more remarkably than other clones. These clones are thought to contribute as genetic material to pear breeding studies.
