摘　　要：为研究诺尼果汁的抗氧化活性的物质基础,以Fe Cl3-K3[Fe(CN)6]比色法测定诺尼果汁不同极性提取物中酚酸的含量,通过清除DPPH自由基、ABTS自由基能力和总抗氧化能力方法,评价其各部分的抗氧化活性。结果表明,抗氧化活性与酚酸含量显著性相关,乙酸乙酯相抗氧化能力最强,可能与其提取物中含有大量的酚酸类化合物有关。Antioxidant activities of Noni juice was studied. Different ploar extracts were obtained from Xisha Noni juice and phenolic acid content was determined by FeCl3-K3[Fe（CN）6] method. Antioxidant activity was evaluated by DPPH scavenging assay, ABTS scavenging assay and total antioxidant capacity assay. It was shown that antioxidant activity of different extracts was significantly positively correlated with total phenolic acid content. Ethyl acetate-soluble fraction showed the strongest ability of antioxidant which may relate to the rich source of phenolic acid content.
