Antioxidant Actibity in Vitro of Zinc Rich Exopolysaccharide from Ganoderm applanatum
摘要
Abstract
Zinc-rich exopolysaccharide (ZEPS) was prepared by submerged fermentagtion of Ganoderm applanatum. The antioxidant activities of ZEPS were evaluated by determining its inhibitory effect on peroxidation of oiol, its scavenging hydroxyl radicals, DPPH ·, superoixide anion. The result showed that the organic zinc reached 0.67 mg/g at ZnSO4 200(j,g/mL, which was 252% higher than that of the control. The organic zinc could greatly enhance the antioxidant capacity of ZEPS. Its capacities of the inhibition of linoleic acid autoxidation, the scavenging of hydroxyl radicals, DPPH and O] were 12.5%, 26.83%, 30% and 20% higher than that of the control, respectively. The antioxidant capacity of ZEPS displayed a dose-response relationship with the concentration of ZEPS.关键词
