Abstract
Antioxidants help fight the harmful effects of free radicals. Although it is well accepted that fruits and vegetables are typical foods rich in antioxidants, no study has however compared the antioxidant capacity of different fruits and vegetables quite well consumed in sub-Saharan Africa and Europe. Also in this work, we propose to evaluate the anti-radical capacity of the juices of some fruits and a spice vegetable widely consumed in Gabon and in Europe, namely: lemon, orange, grapefruit, tomato, pineapple and ginger. The anti-radical activity was measured by scavenging the radical cation of 2, 2′-azinobis [3-ethylbenzothiazoline-6-sulfonic acid] (ABTS•+) with gallic acid as the benchmark antioxidant. The results obtained showed the following variations in anti-radical activity: Local products; ginger > orange and pineapple > grapefruit > tomato > lemon. For imported products; ginger > lemon > grapefruit and orange > tomato. Comparison between local and imported products: local ginger > imported ginger; imported grapefruit ≥ local grapefruit; imported lemon > local lemon; local orange > imported orange; local tomato > imported tomato. In general, the evolution of the anti-radical activity of all fruit juices and spices is as follows: Local ginger > Imported ginger > Imported lemon > local orange > imported grapefruit ≥ imported orange > Local grapefruit > Local tomato > local lemon > Imported tomato. In conclusion, we can say that the fruit and ginger juices from Gabonese soil have an anti-radical activity equivalent or even superior to that of their European counterparts. Ginger juice, whether local or imported, remains the compound endowed with the higher anti-radical activity.
