Vitamin E structure is complex and has many isomers; therefor e, it is difficult to determine it. The results obtained with the several existing determination methods have differences, so it is urgent to find a standard met hod which is fast, accurate and convenient. In this paper, the vitamin E determi nation principles, sample pretreatment and procedure, detecting limit and sensit ivity of spectrophotometry, fluorometry, high pressure liquid chromatography, sq uare-wave voltammetry and oscillographic polargraphy are reviewed. Different is om ers identified by different methods, the advantages and disadvantages and applic ation fields are also discussed. The problems at present, the research direction and focus for the future have been put forward.
