摘 要:葵花籽是是重要的高产油料作物,葵花籽籽油是一种优质的食用油.本文通过气相色谱–质谱分析手段对葵花籽油进行了全组分分析,鉴定出71种化合物,主要为脂肪酸(44.07%)和醇类化合物(44.38%).并采用邻二氮菲法和DPPH法对其抗氧化性能进行了研究.结果表明:葵花籽油清除羟基自由基能力(EC50=30.36±0.20μg/mL)大于2,6二叔丁基4甲基苯酚(BHT)(EC50=436.70±0.02),但清除DPPH自由基(IC50=4.16±0.10 mg/mL)却小于BHT(IC50=0.069±0.002 mg/mL),实验结果表明葵花籽油具有较强的抗氧化活性,且有很好的食品应用价值.The present study investigated the chemical composition and antioxidant activity of Xinjiang sunflower seed oil. The component of the oil was determined by Gas Chromatography-Mass Spectrometry (GC/MS). It was found that the major components are fatty acid (44.07%) and alcohols (44.38%), which constituted over 88% of total content. Antioxidant activities of the sunflower seed oil were characterized by hydroxyl radical (HRSA) and 2,2-diphenyl-l-picrylhydrazyl (DPPH). Results showed that, in HRSA test, the scavenging ability of the sunflower seed oil (EC50=30.36±0.20 μg/mL) showed better activity than that of butylated hydroxytolune (BHT) (EC50=436.7±0.02) showed good activity. But in DPPH assay, antioxidant activity of it (IC50=4.16±0.10 mg/mL) exhibited relatively weak than that of BHT (IC50=0.069±0.02 mg/mL).
