• Tunisian barley varieties
• Total phenolic content
• Antioxidant activities

Four varieties (Rihane, Manel, Roho, and Tej) of Tunisian barley were analysed for their antioxidant activities (AA) using ABTS and DPPH radicals cation, and ferric reducing/antioxidant power (FRAP) methods. The total phenolic (TPC), total flavonoid (TFC) and condensed tannins (CTC) contents were measured. The results indicated that the total phenolic contents ranged from 195.02 +/- 0.32 to 220.11 +/- 0.32 mg gallic acid equivalent/100 g fresh weight. Results showed that Rihane has the highest TPC, TFC and CTC compared to other varieties. Roho barley had a lower activity than Tej barley. A significant correlation (p < 0.05) was found between TPC, TFC, CTC and AA. This study suggests that Tunisian barley varieties may serve as a good source of natural antioxidants.
