  Evaluation and Comparison of the Antioxidative Potency of Various Carbohydrates Using Different Methods

  摘要：

  A detailed analysis of the antioxidative activity of 12 carbohydrates including chondroitin sulfate, fucoidan, agaro-oligosaccharide, 2-deoxy-scyllo-inosose (DOI), Gal beta 1-4DOI, D-glucuronic acid, chitobiose, D-mannosamine, D-galactosamine, D-glucosamine, heparin, and colominic acid was performed using four established methods: 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, ferric reducing antioxidant power (FRAP) assay, superoxide dismutase (SOD) activity assay, and the deoxyribose method. Ascorbic acid and/or catechin were used as positive standards. In the DPPH radical scavenging activity measurements, fucoidan, DOI, and Ga1 beta 1-4DOI showed remarkable levels of activity, although at lower levels than ascorbic acid. The SOD assay revealed that DOI, Gal beta 1-4DOI, and agaro-oligosaccharide had high antioxidant activity, with DOI and Gal beta 1-4DOI notably showing almost half of the antioxidative potency of ascorbic acid. Using the deoxyribose method, chitobiose and heparin showed the highest hydroxyl radical scavenging activity, followed by chondroitin sulfate, colominic acid, Gal beta 1-4DOI, and D-glucosamine. Given that 11 of the carbohydrates analyzed share a common structure, agaro-oligosaccharide being the exception, we propose from our current results that at least one amino, carboxyl, carbonyl, or sulfonyl group is required, but is not in itself sufficient, for carbohydrates to function as antioxidants.
