title: [Determination of plasma tocopherols using high performance liquid chromatography].
abstract: The authors describe an analytical method for the determination of plasma vitamin E by high performance liquid chromatography. 100 microliters of plasma are added to en ethanol-hexane mixture in presence of ascorbic acid. The hexan phase is concentrated and 50 microliters are injected directly into the chromatography in a silica gel column. The detector is set at 280 nm. The very low quantity of plasma required for the determination makes this method very useful in neonatal medicine.
