摘要 以金银花叶和花为原料,将叶与花醇提物添加到食用油脂中,采用Schaal烘箱法,以油脂的过氧化值为评价指标,研究金银花叶与花醇提物对食用油脂的抗氧化作用.结果表明,金银花、叶醇提物能显著抑制玉米油、大豆油、猪油、花生油的氧化,花提取物显著优于叶提取物.对4种油的抗氧化能力由强到弱依次为:大豆油>猪油=玉米油>花生油.花醇提物的抗氧化活性分别是叶醇提物、2,6-二叔丁基-4-甲基苯酚(butylated hydroxytoluene,BHT)、特丁基对苯二酚(tertiary butylhydroquinone,TBHQ)、柠檬酸、抗坏血酸的1.12、1.33、1.19、2.31、1.40倍,叶醇提物的抗氧化活性和TBHQ相当.花、叶醇提物的抗氧化活性随浓度的增加而增强.花醇提物与TBHQ、柠檬酸、BHT、抗坏血酸协同后,其抗氧化能力分别提高了19%、13%、9%、1%.叶醇提物与柠檬酸、BHT和TBHQ复配后,其抗氧化能力分别提高了18%、12%和27%.

Abstract: Honeysuckle's leaves and flowers alcohol extracts were added into edible oil and fats.The antioxidant effects were investigated by Schaal oven method and the peroxide value was used as an evaluation index.The results showed that the alcohol extract from honeysuckle's leaves and flowers had a great antioxidant effects on corn oil,soybean oil,lard oil,peanut oil,flowers extract significantly better than that of leaves extract.Antioxidant effects on four edible oils and fats from strong to weak was:soybean oil > lard oil =corn oil > peanut oil.Antioxidant ability of honeysuckle's flowers extract was 1.12,1.33,1.19,2.31,1.40 times higher than that of leaves;BHT,TBHQ;the antioxidant activity of leaves ethanol extract was the same as TBHQ.Antioxidant activity of flowers and leaves extracts enhanced with the increase of the concentration.When flowers alcohol extract combined with TBHQ,citric acid,BHT,ascorbic acid separately,its antioxidant capacity increased by 19%,13%,9% and 1% respectively.When leaves alcohol extract combined with citric acid,BHT,TBHQ separately,its antioxidant capacity increased by 18%,12% and 27% respectively.
