Abstract: | A rapid, sensitive procedure is described for the analysis of the tocopherols (α-, β-, γ-, and δ-) in plasma, platelets, lipids, and liver using high-performance liquid chromatography and fluorometric detection. Excellent recoveries of these tocopherols in plasma were obtained - greater than 90%. Separation and quantitation of the four tocopherols required as little as 0.2 ml plasma. |
