Abstract: | The antioxidant activity of catechin was amplified by conjugation with amine-terminated polyhedral oligomeric silsesquioxane (POSS) using horseradish peroxidase as catalyst. Compared to intact catechin, the scavenging activity of the POSS-catechin conjugate against superoxide anion was greatly improved. In addition, the conjugate strongly inhibited xanthine oxidase activity. |
