玉米油化学成分及其抗氧化性能研究

Study on Chemical Constituents and Antioxidation Capability of Corn Oil

对玉米油化学成分进行GC-MS分析,共检出7个化合物。以超氧化物岐化酶(SOD)活性为指标探讨其抗氧化作用,并比较几种植物油的抗氧化性能。研究结果表明,鱼油、大豆油和山茶油对于机体抗氧化酶的活性几乎没有影响,而玉米油、葡萄籽油和橄榄油可明显提高机体抗氧化酶的活力,其中以玉米油的作用最为显著。各试验组小鼠肾组织中SOD活力均可提高到青龄组水平,而心肌、肝组织中SOD活力也较老龄组有显著性增强,但却明显低于青龄组。

The corn oil was analyzed by GC-MS and 7 compounds were identified.Based on SOD activity,the antioxidation capability of corn oil compared with kinds of plant oil was suggested in this paper.The results showed that the effect of fish oil,soybean oil and tea seed oil on the SOD activity in mice kidney,liver and heart are very small,while the corn oil,grape seed oil and olive oil can obviously improve activity of SOD.For the all test groups,SOD activity in mice kidney tissue can be increased to young group level,and SOD activity in liver and heart also can be improved to aged group level.
