Antioxidant activities of different fruits (apple, quince, grape, pear and pomegranate) and vegetables (potato, onion, spring onion, red radish and red cabbage) were determined. In addition, total phenolic and flavonoid contents of those samples were assessed. Among fruits, pomegranate had the highest (62.7%) antioxidant activity, followed by quince (60.4%), grape (26.6%), apple (25.7%) and pear (13.7%). The antioxidant activity of vegetables ranged from 40.8% (red cabbage) to 12.5% (onion). Total phenolic and flavonoid contents in fruits varied from 326 to 4306 mg of catechin kg-1 and from 282 to 2115 mg of catechin kg-1, respectively. Those in vegetables ranged between 536 and 2166 mg of catechin kg-1 and between 153 and 842 mg of catechin kg-1, respectively. A high and significant correlation between antioxidant activity and total phenolic content was determined in fruits (r2 = 0.9307, P < 0.01) and vegetables (r2 = 0.9361 P < 0.05). However, flavonoid content was not significantly correlated with antioxidant activity in vegetables, while it was significantly related in fruits (r2 = 0.8316, P < 0.01). It was observed that total phenolic content is the major contributor to the antioxidant activity of fruits and vegetables.
Abstract
Antioxidant activities of different fruits (apple, quince, grape, pear and pomegranate) and vegetables (potato, onion, spring onion, red radish and red cabbage) were determined. In addition, total phenolic and flavonoid contents of those samples were assessed. Among fruits, pomegranate had the highest (62.7%) antioxidant activity, followed by quince (60.4%), grape (26.6%), apple (25.7%) and pear (13.7%). The antioxidant activity of vegetables ranged from 40.8% (red cabbage) to 12.5% (onion). Total phenolic and flavonoid contents in fruits varied from 326 to 4306 mg of catechin kg-1 and from 282 to 2115 mg of catechin kg-1, respectively. Those in vegetables ranged between 536 and 2166 mg of catechin kg-1 and between 153 and 842 mg of catechin kg-1, respectively. A high and significant correlation between antioxidant activity and total phenolic content was determined in fruits (r2 = 0.9307, P < 0.01) and vegetables (r2 = 0.9361 P < 0.05). However, flavonoid content was not significantly correlated with antioxidant activity in vegetables, while it was significantly related in fruits (r2 = 0.8316, P < 0.01). It was observed that total phenolic content is the major contributor to the antioxidant activity of fruits and vegetables.
