title: Application of a high-performance liquid chromatographic fluorescence method for the rapid determination of alpha-tocopherol in the plasma of cattle and pigs and its comparison with direct fluorescence and high-performance liquid chromatography-ultraviolet detection methods.
abstract: High-performance liquid chromatography is used to develop a sensitive method for the determination of tocopherol levels in the plasma of cattle and pigs. This method is compared with a similar method using UV detection and one using direct fluorescence determination of tocopherol. Finally a double injection technique used in conjunction with fluorescence detection is shown to enhance the rate of analysis of the tocopherol levels in bovine plasma extracts.
