Malonaldehyde determination in tissues and biological fluids by ion-pairing high-performance liquid chromatography
A method for the analysis of malonaldehyde by ion pairing high-performance liquid chromatography is described. The method is direct; no thiobarbiturate chromogen formation is required, and sample… Expand
A highly sensitive high-performance liquid chromatography method for the estimation of ascorbic and dehydroascorbic acid in tissues, biological fluids, and foods.
A highly sensitive procedure for determining ascorbic acid (AA) and dehydroascorbic acid (DHAA) by high-performance liquid chromatography with electrochemical detection in biological fluids, tissues,… Expand
Distribution of alpha-tocopherol in human plasma lipoproteins.
Lipoproteins were removed from human plasma by ultracentrifugation at a density of 1.225. Three classes of lipoproteins were then separated by 4% Agarose-column chromatography: very low density… Expand

A 90-day feeding study with gerbils was conducted to evaluate the influence of dietary vitamin E levels (25 mg/kg diet, 75 mg/kg, 300 mg/kg, and 900 mg/kg), two levels of dietary methionione (casein… Expand
Mechanisms of Absorption, Transport and Tissue Uptake of RRR-α-Tocopherol and d-γ-Tocopherol in the White Rat
The metabolism of alpha- and gamma-tocopherol was studied in three groups of rats that were fed a modified AIN-76 diet containing normal (NE, 0.2 g alpha-tocopherol/kg), high (HE, 1.0 g… Expand
Vitamin E levels in superficial and intra-abdominal locations of white adipose tissue in the rat
Concentrations of RRR-α-tocopherol (vitamin E) were measured in white adipose tissue (WAT) from three superficial and three intra-abdominal locations of rats fed diets using low-, normal-, or… Expand
Alpha- and gamma tocopherol concentrations in human serum.
Vitamin E (alpha- and gamma-tocopherol) and total lipid concentrations were determined in the serum of 451 healthy human male and female subjects ranging in age from 19 to 70 years. Mean serum… Expand
A Procedure for the Separation and Quantitative Analysis of Ascorbic Acid, Dehydroascorbic Acid, Isoascorbic Acid, and Dehydroisoascorbic Acid in Food and Animal Tissue
Abstract A procedure is presented for the direct and simultaneous determination of ascorbic acid (AA) and isoascorbic acid (IAA) in food products and animal tissues by reverse phase high-performance… Expand
Vitamin C and vitamin E status in the spontaneously diabetic BB rat before the onset of diabetes.
Ascorbic acid (AA), dehydroascorbic acid (DHAA), and vitamin E were measured in tissues and plasma of 30 control and 30 spontaneously diabetic BioBreeding rats (BBdp) during development and before… Expand
