维生素E(VE,即生育酚)是天然脂溶性抗氧化剂,对机体有一定的保护作用。摄入不足或某些疾病时,血清VE含量降低,服用VE则血清VE含量升高。 VE使Fe~(3+),还原成Fe~(2+),Fe~(2+)与联苯菲哕啉结合成粉红色复合物的分光光度法,方法简便,回收率及重复性较好,适于一般实验室应用。文中讨论了一些影响测定的因素。 Vitamin E (VE, that is, tocopherol) is a natural fat-soluble antioxidants, the body has a protective effect. Inadequate intake or certain diseases, serum VE decreased, taking VE serum VE levels increased. VE Fe ~ (3 +), reduced to Fe ~ (2 +), Fe ~ (2+) combined with diphenanthroline into a pink complex spectrophotometry, the method is simple, the recovery rate and repeatability Good, suitable for general laboratory applications. The paper discusses some of the factors that affect the determination.
