Antioxidant Properties of Polysaccharides from Phellinus igniarius in vitro
摘要
Abstract
The antioxidant properties of intracellular polysaccharides（IPS） and exopolysaccharides（EPS） from Phellinus igniarius were evaluated in vitro by chemical simulation.The results indicated that the EC50 of Phellinus igniarius IPS and EPS were 1.09 mg/mL and 1.52 mg/mL for scavenging DPPH radicals,0.78 mg/mL and 0.23 mg/mL for scavenging hydroxyl radicals,29.97μg/mL and 20.31μg/mL for scavenging superoxide anion radicals and 1.36 mg/mL and 1.66 mg/mL for chelating Fe2＋,respectively.An excellent linear relationship between the reducing power and concentrations of both polysaccharides was observed in the tested concentration ranges.The antioxidant capacity of both polysaccharides was in a dose-dependent manner but showed an obvious difference.关键词
