| description | <p>This study was carried out to determine the amount of total phenols, total flavonoid and antioxidant activity of 7 grape cultivars grown in Kurdistan rejoin of Iraq. The results showed that total phenols, flavonoid and antioxidant activity in the berries varied among the investigated cultivars. Total phenolic content, total flavonoid content ranged from 112.77 to 249.19 mg GAE/100g FW, 584.23 to 288.55 mg of rutin equivalents/100 g of (fresh sample) respectly and antioxidant capacity value ranged from 41.79 to 92.30%. Tahlik cultivar had the highest value of antioxidant capacity, flavonoid and total phenolic content. The lowest total phenolic, flavonoid content and the lowest value of antioxidant capacity were found in Abhar cultivar. Present results showed statistically significant correlations with the free radical scavenging activity. There was a very strong positive correlation (R² =1, <em>p </em><0.05) between the antioxidant activity and total phenolic content and a strong positive correlation (R² =0.9735, <em>p</em> <0.05) between the antioxidant activity and total flavonoid content.</p><p> </p> |
