In this paper, five kinds of peel extracts of five varieties (wide-skin orange, sweet orange, pomelo, lemon and kumquat) were used as the raw materials to evaluate the antioxidant capacity of each variety. The anti-oxidation ability of Citrus peel extracts was determined by the DPPH method and ABTS method respectively. The antioxidant capacity of IC50 was used to evaluate the antioxidant activity of Citrus, and the antioxidant capacity of Citrus peel of various varieties was comprehensively analyzed. The Citrus peel had strong antioxidant activity and there were some differences between the varieties. The antioxidant capacities of the peels were different, and the comprehensive antioxidant capacities were from high to low: Ota citrus, Jindan, Beijing lemon, Newhall navel orange, Pingshan pomelo. Among the five citrus varieties, the broad-skin orange had the strongest antioxidant capacity, followed by the kumquat, the lemon and sweet orange, and the pomelo had the weakest antioxidant capacity.

Key words: Citrus, peels, extracts, antioxidant capacity
