The effects of LDYE on the turgidity of mitochondria,the fluidity of membrane,the activity of cytochrome C oxidase and ATPase at subcellular level were investigated by using H\-2O\-2/Fe\+\{2+\} -induced mitochondria damage model system. It was found that the small peptide exhibited an obvious ability of removing free radicals and protecting the mitochondria from damage by oxidation. [WT5HZ]展开更多
目的:研究芦荟不同溶剂超声微波协同萃取提取物对菜籽油、猪油、棉籽油及葵花油的抗氧化作用。方法:以无水乙醇、蒸馏水及无水乙醇-蒸馏水(体积比为1∶1)为溶剂,采用超声微波协同萃取提取,采用743 Ranc im at食用油氧化稳定性测定仪分...目的:研究芦荟不同溶剂超声微波协同萃取提取物对菜籽油、猪油、棉籽油及葵花油的抗氧化作用。方法:以无水乙醇、蒸馏水及无水乙醇-蒸馏水(体积比为1∶1)为溶剂,采用超声微波协同萃取提取,采用743 Ranc im at食用油氧化稳定性测定仪分别测定提取物对菜籽油、猪油、棉籽油及葵花油的抗氧化作用。结果:不同溶剂提取物对油脂的抗氧化性存在差异;无水乙醇提取物抗氧化作用明显,并随提取物加入量的增加抗氧化性有提高的趋势,但对不同的油脂抗氧化性也存在一定的差异。结论:芦荟无水乙醇提取物可以作为菜籽油的抗氧化添加物,具有研究开发价值。展开更多
