  • Title: In vitro antioxidant activity of acetylated and benzoylated derivatives of polysaccharide extracted from Ulva pertusa (Chlorophyta).
    Author: Qi H, Zhang Q, Zhao T, Hu R, Zhang K, Li Z.
    Journal: Bioorg Med Chem Lett; 2006 May 01; 16(9):2441-5. PubMed ID: 16481163.
    Abstract:
    The antioxidant activity of natural ulvan and its derivatives (acetylated and benzoylated ulvans) in vitro was determined, including scavenging activity against superoxide and hydroxyl radicals, reducing power, and chelating ability. Obvious differences in antioxidant activity between natural ulvan and its derivatives were observed, moreover, the antioxidant activity of acetylated and benzoylated ulvans was stronger than that of natural ulvan.
