The antioxidant potency of components from Xylaria gracillima in submerged culture was investigated,employing various established in vitro systems,such as superoxide(O2.-)and hydroxyl(OH)radical scavenging,reducing power,and ferrous ion chelating ability.Tocopherol(Ve),butylated hydroxytoluene (BHT)and ethylenediaminetetraacetic acid(EDTA)were used as positive controls.According to the results,components from X.gracillima in submerged culture showed significant effect on ferrous ion chelating ability,O2.-and .OH radical scavenging ability at the range of concentration tested,and their highest antioxidant activities reached 89.72
