Differential depletion of carotenoids and tocopherol in liver disease
Maria A. Leo, Alan S. Rosman, Charles S. Lieber – 1 June 1993 – Carotenoids and tocopherols are major natural protective agents against free radical–mediated liver damage, but their levels in diseased liver are largely uncharted. Therefore we carried out measurements with high‐pressure liquid chromatography of α‐ and β‐carotene, lycopene, cryptoxanthin, lutein and zeaxanthin, total retinoids and α‐ and γ‐tocopherol. Liver tissue was obtained from percutaneous needle biopsies, livers of transplant recipients or a donor bank.
