Abstract

The study on the in vitro antioxidant activity of garlic green pigments was conducted with four different in vitro antioxidant models,they were hydroxyl radical system,superoxide anion system,DPPH system and ABTS system.The results showed that the pigments presented antioxidant activity on all of the four radicals.As the concentration of garlic green pigments raised,the rate of radical scavenging increased significantly.The ability of garlic green pigments on scavenging free radical were ranked as follows: hydroxyl radicals superoxide anion radicals ABTS radicals DPPH radicals.
