Abstract

A salt solution for stabilization of the tocopherols in plasma is introduced. A lenient method for extraction of lipids of this kind is described. The method of colorimetric determination according to Emmerie and Engel is modified in using a mixture of acetone, benzene and water. These substances do not interfere with the reaction components, thus, giving extinction values constant for hours, and allowing exact determinations of tocopherols. Corrections for carotenes are to be done and annotated.
