This study was investigated to analyze the antioxidant activity or extracts form Elaeagnus multiflora Thunb for development to the functional materials. The antioxidative activities of water ethanol and methanol extracts from the Elaeagnus multiflora Thunb were analyzed by electron donating ability (EDA), anti-oxidization activity, superoxide dismutase (SOD)-like activity, The superoxide anion radical-scavenging activity, and nitrite scavenging ability. The Etectron donating ability of methanol extract was higher in 1.0 mg/mL of extraction solution than those of ethers. The anti-oxidization activity of ethanol and methanol extracts by thiocyanate method using linolenic acid system was higher than those of the water extract. The SOD-like activity was increased with increase of the extract concentration in each extracts. The SOD-like activity was highest in 2.0 mg/mL of methanol extract. The superoxide anion radical-scavenging activity was increased with increase of the concentration in the ethanol extract and methanol extract. The nitrite scavenging ability of water extracts in 1.0 mg/mL of extraction soiution in pH 1.2 was higher than ethanol extrats and methanol extracts. The nitrite scavenging ability of all extracts was decreased according to increase of pH.
