Monitoring of Ubiquinol-10, Ubiquinone-10, Carotenoids, and Tocopherols in Neonatal Plasma Microsamples Using High-Performance Liquid Chromatography with Coulometric Electrochemical Detection

A method for measuring the lipophilic antioxidants α-tocopherol, γ-tocopherol, ubiquinol-10, ubiquinone-10, β-cryptoxanthin, and β-carotene in 5 or 10 μl neonatal plasma is presented. First lipid extraction together with the internal standards γ-tocotrienol, ubiquinone-7, ubiquinol-9, ubiquinone-9,...
