摘要：PROBLEM TO BE SOLVED: To provide a method for speedily analyzing tocopherols capable of separately analyzing bothα-tocopherol andγ-tocopherol contained in a sample and efficiently and accurately analyzing a large number of samples in an extremely short time. SOLUTION: Alcohol of carbon numbers 3-5 is added to the sample, sufficiently agitated, and centrifuged to acquire a supernatant liquid, separateα-tocopherol andγ-tocopherol by an HPLC, and analyze them. It is preferable to use isoprophyl alcohol as the alcohol and perform analysis by an reversed phase HPLC. COPYRIGHT: (C)2004,JPO&NCIPI
