  • METHOD AND APPARATUS FOR ANALYZING VITAMIN E IN LIPOPROTEINS
    Publication number: 20120058549
    Abstract: A method of analyzing vitamin E components in a lipoproteinby subjecting a lipoprotein-containing sample to ion exchange chromatography to separate the lipoprotein, reacting the separated lipoprotein to a pretreating solution containing an organic solvent and a surfactant to liberate vitamin E components, and then subjecting the liberated vitamin E components to reverse phase chromatography. Also described is a method of judging various pathological conditions such as the pathological conditions of diabetes, the risks of coronary artery diseases, and the pathological conditions of myocardial infarction using levels of vitamin E components in the lipoprotein as an index.
