Abstract:
A method for evaluating antioxidant activities of different varieties of citrus was developed based on the strong inhibition of the antioxidant constituents on the chemiluminescence of luminol-NaClO system，and the antioxidant activities of four kinds of citrus were determined. Antioxidant activities of citrus were evaluated according to IC50. The results showed that all of the tested citrus had good antioxidant activities, among which the sweet orange showed the highest acivity, followed by green tangerine and orange Shatang. And the weakest activity was found with kumquat. The method based on chemiluminescence of luminol-NaClO system was efficient, rapid and can widely used in evaluating the antioxidant activities of varieties of fruits or other food.
