Abstract: In this study, methyl violet assay, MDA determination and SDS-PAGE were used to investigate antioxidative activities of five natual products. The hydroxyl radical scavenging ability, protections against lipid peroxidation and protein oxidation were measured. The results showed that five natual products exhibited different antioxidative activities in different reactive systems. Alizarin red has the strongest effect in hydroxyl radical scavenging and protein oxidation protection. Resveratrol exhibit strongest inhibition to lipid peroxidation. The results also reflect the dissolve nature of compounds play a role in its antioxidation system.

Key words: antioxidation, hydroxyl radical, lipid peroxidation, protein oxidation, antioxidative activity
