Trolox标准曲线,配制不同浓度的Trolox甲醇溶液进行测定,以吸光值和Trolox浓度制作标准曲线,得到吸光值(y)和Trolox(x)之间的回归方程。从而测定物质的抗氧化活性。  Trolox即水溶性维生素E,化学名称:6-羟基-2,5,7,8-四甲基色烷-2-羧酸(6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylicacid)  基本描述:白色、灰白色或者淡黄色固体,一种细胞通透的\水溶性的VE类似物,具有抗氧化的性质.可以预防过氧化亚硝酸盐导致的氧化胁迫和老鼠腺细胞的凋亡.(Whitetooff-whiteorpaleyellowsolid.Acell-permeable,water-solublederivativeofvitaminEwithantioxidantproperties.Preventsperoxynitrite-mediatedoxidativestressandapoptosisinratthymocytes.) 作为一种有效的三线态淬灭剂可以改善荧光分子的光物理性质。


Trolox standard curve was measured by preparing Trolox methanol solution with different concentration, and the regression equation between the absorption value (y) and the Trolox (x) was obtained by making the standard curve with the absorption value and the Trolox concentration. The antioxidant activity of the substance was determined. Trolox is water-soluble vitamin E, chemical name: 6-hydroxy-2,5,7,8-tetramethylchromate-2-carboxylic acid 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxy acid A cell-permeable, water-soluble VE analogue with antioxidant properties. It can prevent peroxynitrite-induced oxidative stress and apoptosis of mouse glandular cells.Whitetooff-whiteorpaleyellowsolid.Acell-permeable,water-solublederivativeofvitaminEwithantioxidantproperties.Preventsperoxynitrite-mediatedoxidativestressandapoptosisinratthymocytes.)
