Routine assay for determination of alpha-tocopherol in liver.
Journal of Lipid Research, 1980 A rapid and accurate procedure for determination of alpha-tocopherol in liver has been developed. Extracts of saponified liver homogenates were purified by a simple and efficient chromatography step on Kieselgel.

Scientific Opinion on the safety and efficacy of synthetic alpha-tocopherol for all animal species [PDF]
EFSA Journal, 2012 <p>The additive synthetic alpha-tocopherol consists of pure all-rac-alpha-tocopherol. In a previous opinion on the safety and efficacy of vitamin E for all animal species, the FEEDAP Panel assessed the safety of the acetate ester of the additive ...

The uptake of tocopherols by RAW 264.7 macrophages
Nutrition Journal, 2002 Background Alpha-Tocopherol and gamma-tocopherol are the two major forms of vitamin E in human plasma and the primary lipid soluble antioxidants. The dietary intake of gamma-tocopherol is generally higher than that of alpha-tocopherol.

Annals of Nutrition and Metabolism, 1999 We wanted to determine whether alpha-tocopherol supplementation to pregnant rats could increase the concentration of alpha-tocopherol in maternal and fetal plasma and tissues. Pregnant rats were treated with alpha-tocopherol on days 18 and 19 gestation and studied at day 20. A control group was studied in parallel. Treatment of pregnant rats with alpha-
