Antioxidant Activity of Lactoferrin in vitro

Abstract

Abstract: The in vitro antioxidant activity of lactoferrin was evaluated by spectrophotometrically measuring its lipid peroxidation inhibitory activity and scavenging capacities against and hydroxyl and DPPH free radicals. Lactoferrin had obvious lipid peroxidation inhibitory activity and scavenging activities against hydroxyl and DPPH free radicals. in the following decreasing order: lipid peroxidation ＞ hydroxyl free radical ＞ DPPH free radical. The free radical scavenging mechanism may be due to the interaction between lactoferrin and iron ion, which is necessary for reaction systems.

Key words: lactoferrin, anti-lipid peroxidation activity, hydroxyl radical scavenging activity, DPPH radical scavenging activity
