Abstract Background Direct measurement of the bioavailable α-tocopherol content presents a significant analytical challenge and requires chiral separation stereoisomers. Objective The objective study was to validate an method for analysis stereoisomers in infant formulas dairy products. Method Samples were saponified at elevated temperature lipophilic components extracted into organic solvent, ...

noise induced hearing loss (nihl) is one of the most important occupational disease worldwide. nihl has been found potentiate by simultaneous carbon monoxide (co) exposure. free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the co hypoxia. this study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

BACKGROUND/OBJECTIVES Vitamin E is a fat-soluble vitamin and functions primarily as a lipid antioxidant. Inadequate vitamin E status may increase risk of several chronic diseases. Thus, the objectives of this study were to estimate intake and plasma concentration of each tocopherol and to evaluate vitamin E status of Korean adults. SUBJECTS/METHODS Three consecutive 24-h food recalls and fast...

BACKGROUND Little is known about α-tocopherol's bioavailability as a constituent of food or its dependence on a subject's age. OBJECTIVE To evaluate the α-tocopherol bioavailability from food, we used collard greens grown in deuterated water ((2)H collard greens) as a source of deuterium-labeled ((2)H) α-tocopherol consumed by younger and older adults in a post hoc analysis of a vitamin K stu...

A simple, sensitive and rapid spectrofluorimetric method for determination of α-tocopherol in pharmaceutical capsule and human plasma was developed and validated. The native fluorescence of α-tocopherol was measured at 334 nm with excitation at 291 nm, after extraction of α-tocopherol from human plasma hexane:dichloromethane mixture. The calibration curves were linear (R≥0.9993) in the concentr...
