[Determination of tocopherols in oils of mixed tocopherol as food additive using reverse-phase high-performance liquid chromatography].
Simultaneous determination of four tocopherols was developed using reverse-phase high-performance chromatography with a mixture of methanol and water (88:12) as a mobile phase. The alpha-, beta-, gamma- and delta-tocopherols in oils of mixed tocopherol as food additive were determined. It is clarified that the proposed method is useful for the quality control of food additive.
