Analysis of water-soluble antioxidants by high-pressure

We quantified three water-soluble antioxidants by high-pressure liquid chromatography with electrochemical detection (h.p.l.c.-e.c.). Current-voltage relationships made at various settings of the D2 porous graphite electrode help to identify ascorbic acid, glutathione and uric acid.

Water- and Fat-Soluble Antioxidants in Human Seminal Plasma

SP and serum samples were properly processed and analyzed by HPLC methods suitable to determine water (ascorbic acid, glutathione (GSH) and uric acid) and fat-soluble (all-trans-retinoic acid, all-trans-retinol, α-tocopherol, carotenoids and coenzyme Q 10) antioxidants. Data demonstrate that only ascorbic acid is higher in SP than in serum (SP

Tear fluid content of electrochemically active components

Ascorbic acid (AA) is found at 665 microM, tyrosine at 45 microM and glutathione (GSH) at 107 microM. Cysteine (48 microM) and uric acid (328 microM) are reported for the first time; the latter is somewhat controversial as a physiologically active antioxidant. One peak on the chromatogram was consistently present but has not been identified.

Similarly, the water-soluble antioxidant, ascorbic acid, could enter the mucosa at the apical surface as a dietary component from the intestinal lumen or, alternatively, could arrive via the circulation at the baso-lateral face of the enterocytes following its synthesis in the avian kidney (Chatterjee et al., 1975).

Antioxidants, Oxidative Damage and Oxygen Deprivation Stress

The central role of GSH in the antioxidative defence is due to its ability to regenerate another powerful water‐soluble antioxidant, ascorbic acid, via the ascorbate–glutathione cycle (Foyer and Halliwell, 1976; Noctor and Foyer, 1998).
