Antioxidant activity of fermentation broth extracts of Verticicladium trifidum from Fortunearia sinensis

  • 摘要: 为了探讨筛选出的具有较高总抗氧化活性的牛鼻栓三裂轮簇霉菌(Verticicladiumtrifidum)发酵液提取物,本研究制备了菌株发酵液粗提取物,比较了其抗脂质过氧化作用和清除超氧阴离子自由基(O-2.)、羟自由基(.OH)、二苯基苦基苯肼自由基(DPPH.)的能力。结果表明:该菌株发酵液提取物的抗氧化活性不仅高于阳性对照芦丁,而且具有良好的稳定性。浓度为1.0mg/mL时,对.OH具有一定的清除作用,但弱于芦丁,清除率为74.12%;对O-2.和DPPH.均具有较强的清除作用,清除能力优于芦丁,清除率分别达到84.25%和84.27%。
