以过氧化值(POV)为指标研究了新疆地方常见的特色药食两用植物黑种草籽提取物对菜籽油的抗氧化作用。结果表明:黑种草籽乙醇提取物及乙酸乙酯提取物对菜籽油都有一定的抗氧化作用,其抗氧化效果随提取物添加量的增大而增强;乙醇提取物的抗氧化活性强于乙酸乙酯提取物的抗氧化活性;乙醇提取物与VC、VE、柠檬酸有较明显的协同作用,抗氧化效果均好于单独使用。 The peroxide value (POV) was used as an index to study the anti-oxidative effect of extracts of black seeds of common herbaceous and edible plants, Xinjiang, on rapeseed oil. The results showed that ethanol extract of black seed and ethyl acetate extract had certain antioxidative effect on rapeseed oil, and its antioxidant activity increased with the addition of extract; the antioxidant activity of ethanol extract Stronger than the ethyl acetate extract antioxidant activity; ethanol extract with VC, VE, citric acid have a more significant synergistic effect, antioxidant effect were better than used alone.
