Özet
Edible greens, especially wild greens, play an important role in traditional diets and are rich in phenols and other compounds. The purpose of this study was to investigate total phenolic content (TPC) and antioxidant activities of ethanolic extracts from wild and cultivated Rumex acetosella L. The wild sheep sorrel extract inhibited lipid peroxidation and 1,1-diphenyl-2-picrylhydrazyl radical with EC50 values of 0.02 and 3.67mgml(-1); however, the EC50 values for cultivated sheep sorrel extract were 0.76 and 21.94mg ml(-1). In the reducing power assay, the values of measured absorbance were 0.723 and 0.430 for wild and cultivated extracts, respectively, at 1mgml(-1) concentration. The chelating of ferrous ions by the wild and cultivated sheep sorrel was determined as 59.4% and 56.2%, respectively, at 1mgml(-1) concentration. TPC of wild and cultivated sheep sorrel was found to be 69.21 +/- 8.5 and 57.57 +/- 1.8mg gallic acid equiv. g(-1) extract, respectively. There is a positive correlation between phenolic content and antioxidant assays. The results obtained in this study indicate that wild R. acetosella could be an important dietary source because of its good antioxidant properties.
