The two main sources of vitamins for humans are food and commercially available multivitamin supplements or vitamin drinks. Water-soluble vitamins include the B- vitamins and vitamin C. The main goal of this study was to perform a separation of seven water-soluble vitamins without the use of ion-pair reagents. A secondary goal was to positively identify and quantitate some of these vitamins to demonstrate that the method is useful for quantitation in commercially available vitamin supplements and drinks. The effect of decreasing particle size on separation time, pressure, and sensitivity was investigated using three chromatographic columns of different dimensions and particle size, but made of the same base type silica.

Ascorbic acid and malondialdehyde levels are two important parameters for the measurement of oxidative stress in biological systems. Ascorbic acid is an important antioxidant from dietary sources. Malondialdehyde, one of the major secondary oxidation products of peroxidized polyunsaturated fatty acids, has been shown to be of biological significance. A new method for measurement of ascorbic acid and malondialdehyde was tested with the same analysis conditions in human serum from diabetic patients and healthy individuals. Ascorbic acid and malondialdehyde levels of patients with diabetes mellitus were significantly different from the controls. The detection limits for ascorbic acid and malondialdehyde were 1.3 × 10-8 mol/I, and 1.02 × 10-8 mol/L, respectively. This simple, rapid, and sensitive method is useful for clinical measurements.
