Abstract：Themonosaccharidecompositionofpolysaccharidesfromfourdiferentparts（oldstem，youngstem，oldleaf，andyoung leaf）of Erythropalumscandens Bl.wasdeterminedusing pre-columnderivatizationhigh-performance liquidchromatogaphy（HPLC）. Their antioxidant properties were comprehensively evaluated by assesing the scavenging capacities against DPPH ⋅⋅ ，ABTS ，and superoxideanionradical（O·），aswellasteferrcionreducingantioxidantpower（FRAP）assa，toscreenforhighlyctivepolysaccharide components.TheresultsshowedthatErythropalumscandenspolysaccarides were primarilycomposedof ten monosaccharides：Namelymase，lucosamine，ibse，amose，glucuroniccid，galacturoniccid，glucose，galactose，yloedbi nose.Xylosewasnotdetectedintheyoungstempolysaccharides，utwaspresentinteoldstem，oldleaf，andyoungleafpolsachrides.The total sugar contentfollowed the order of old stem > young stem > young leaf > old leaf.The in vitro antioxidant assays indicated that polysaccharides from allparts exhibited scavenging activity against DPPH·，ABTS +⋅ ，and 02- ·，as well as ferric ion reducing power.Among them，theold stem polysaccharide demonstratedsuperiorantioxidantactivitycompared to theotherparts.
