摘　　要：利用DPPH自由基清除法、羟自由基清除法、超氧阴离子自由基清除法、总还原力的测定4种方法对腐植酸钠的抗氧化活性进行了检测和评价。研究结果表明,腐植酸钠具有较强的自由基清除能力和一定的抗氧化能力,且随着腐植酸钠浓度的增加,其抗氧化能力逐渐增强。The antioxidant activity of sodium humate was detected and evaluated by DPPH radical scavenging method, hydroxyl radical scavenging method, superoxide anion radical scavenging method and total reducing force determination method. The results showed that sodium humate had strong free radical scavenging ability and certain antioxidant capacity, and with the increase of sodium humate concentration, its antioxidant capacity was gradually enhanced.
