Composition of Two Seaweed-Oligosaccharide-Lysates Derived from Agarase As-II and Their Ferrous-Chelating Antioxidant Power
並列摘要
Seaweed-oligosaccharide-lysates (SwOSLys) Gra-C108, Mon-C108, Gra-AS-II, or Mon-AS-II are seaweed polysaccharide extracts (SwPSExts) Gra or Mon, which are digested by either Aeromonas (A.) salmonicida MAEF108 crude agarases or Agarase AS-II that was produced from marine bacteria A. salmonicida MAEF108. High-performance liquid chromatography revealed that there were neoagarohexaose and neoagarotetraose in both Gra-C108 and Gra-AS-II and that neoagarooligosaccharide was absent in both Mon-C108 and Mon-AS-II. The polyphenol content of SwOSLys was higher than that of SwPSExts, though without significant difference (p＜0.05) on lysates, as digested by crude MAEF108-agarases or Agarase AS-II. Comparison of the chelating effects of GraC108 and Gra-AS-II on Fe(superscript 2+) shows that not only do the polyphenolic compound but also the neoagarooligosaccharide show antioxidative properties.
