摘要
研究粗壮女贞苦丁茶提取物在不同试验体系及细胞和食品层面的抗氧化活性,为其在食品工业的高附加值开发利用提供理论基础。通过体外化学分析法系统测定提取物的自由基清除作用、脂质过氧化抑制效应及还原能力;分别以PC12细胞、花生油和猪油为模型,评价提取物对细胞氧化损伤及食用油脂氧化酸败的抑制效果。结果表明:粗壮女贞苦丁茶提取物具有较强的还原能力,可有效清除受试自由基,并抑制脂质过氧化反应的发生,具有优良的抗氧化活性;试验条件下,提取物可显著抑制并修复PC12细胞的氧化损伤,亦能有效延缓食用油脂的氧化酸败。
The antioxidant activity of Ligustrum robustum（Rxob.） Blume extracts（LRE） was investigated in various testing systems and models of cell and food,which could provide the theoretical basics for the valuable application of LRE in food industry.The free radical scavenging activity,lipid peroxidation inhibition and reducing power of LRE were determined by chemical analysis method.Meanwhile,the inhibitions of LRE on the oxidative injury of cell and the oxidative rancidity of edible oil were also evaluated in the models of PC12 cell,peanut oil and lard.All results suggested that LRE possessed the excellent antioxidant activity with the strong reducing power,free radical scavenging capacity and the lipid peroxidation inhibition.Moreover,LRE could effectively inhibit the oxidative injury of PC12 cells and delay the oxidative rancidity of edible oil.
