Using the DPPH free radical,hydroxyl free radical(·OH) elimination abilities and the linoleic acid antioxidants system,wild plum skin pigment of the antioxidant activity was studied by Ultraviolet spectrophotometry.The result indicated that the antioxidant activities of the wild pigment was fine.The DPPH free radical elimination rate of pigments approached 92.7% of Vc.The suppression rate of Pigments to the linoleic acid was equal to 88.53% of VE and 79.31% of Vc.
