Abstract
The aim of this study was to analyze the total phenolic content and antioxidant activity of refrigerated nettle drinks stored at 4°C for 3 months. The antioxidant properties determined by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assays and total phenolic contents of the nettle drinks were evaluated using Folin-Ciocalteu method. In addition, correlations between antioxidant activity and total phenolic content were assessed. The results showed a significant increase for the refrigerated nettle drinks (p<0.05) in the case of total phenolic content and antioxidant activity in two months. It was concluded that the nettle drink should be treated as a short shelf-life product (2-month)
