%X The content of polysaccharide from leaves, branches and seeds of endangered plants <em>Elaeagnus mollis</em> Diels was determined by the phenol-sulfuric acid method under 490 nm. The oxygen anion radical and hydroxyl radical scavenging activity of polysaccharide from three parts of <em>E.mollis</em> was studied by the pyrogallol self-oxidation method and spectrophotometry with safranine O&mdash;Mn<sup>2+</sup>&mdash;H<sub>2</sub>O<sub>2</sub> system. The results showed that the average levels of polysaccharide from leaves, branches and seeds of <em>E.mollis</em> were 69.42, 23.15 and 56.47 mg&middot;g<sup>-1</sup>, respectively. The polysaccharide of three parts showed antioxidant activities in removing superoxide free radicals and hydroxyl radical. The scavenging activity on superoxide free radicals was Vc&gt;seeds&gt;branches&gt;leaves, removing hydroxyl radical activity was leaves&gt;seeds&gt;Vc&gt;branches. The research results showed that the leaves and seeds of <em>E.mollis</em> could be the raw material as natural antioxidant.
