Summary
Simultaneous determination of alpha-tocopherol, gamma-tocopherol and delta-tocopherol by reversed-phase liquid chromatography (RP-HPLC) with UV detection in various infant milk formulas sold in Turkey was performed. Analytical method parameters confirmed the quality of the method. Tocopherol isomers in 15 infant formulas ranged from 8.73+/-0.09 to 27.02+/-0.06 mg alpha-tocopherol in 100 g(-1), from 1.67+/-0.04 to 7.28+/-0.10 mg gamma-tocopherol in 100 g(-1); from 0.87+/-0.05 to 1.81+/-0.03 mg delta-tocopherol in 100 g(-1).
