The determination of tocopherols and isoprenoid quinones in the grain and seedlings of wheat (Triticum vulgare).

Abstract

1. A comparison is made of several procedures for the extraction of tocopherols and isoprenoid quinones from plant tissues. 2. Gradient-elution column chromatography on acid-washed alumina efficiently separates the isoprenoid quinones and tocopherols into groups that can then be assayed spectrophotometrically or, with the tocopherols, separated into their individual components and determined by gas-liquid chromatography. 3. This improved analytical procedure was used to study the distribution of the tocopherols and of ubiquinone in the ungerminated wheat grain.
