Abstract: Objective The effects of anthocyanin pigment from maize purple plant on resisting lipid peroxidation were investigated.Methods The inhibition of anthocanin pigment from maize purple plant was examined in vitro that autcoxudation of lecithin liposome system induced by Fe²⁺ .50 mice were randomly divided into 5 groups.Vehicle and different dose anthocyanin pigment from maize purple plant were given respectively,and then experimental injury of mice liver was induced to make use of bromobenzene and the content of MDA was determined in liver homogenate.Results The inhibition rates of an2 thocyanin pigment from maize purple plant on linoleic acid oxidation was higher that of ascorbic ascorbic acids.The content of MDA in homogenate in middle and high dose of pigment were significantly lower than that in low dose and the injured control group.There were no significat differences in the content of MDA in homogenate between low dose group and injury control group.Conclusion The anthocyanin pigment from maize purple planthave the capability to resist lipid peroxide.
