Antioxidant Activity and Component Analysis of Ethanol Extract from Laetiporus sulphureus
The antioxidant activity of ethanol extract from Laetiporus sulphureus was evaluated by the 1,1-diphenyl-2-picrylhydrazyl(DPPH),hydroxyl,2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS),and superoxide anion radicals scavenging ability and reducing power.The results showed that the ethanol extract of Laetiporus sulphureus could effectively scavenge the DPPH,hydroxyl,ABTS,and superoxide anion radicals with the EC50 values of 820.20 μg/mL,3.81 mg/mL,317.09 μg/mL,and 7.31 mg/mL,respectively.The alcohol extract of Laetiporus sulphureus also had reduction capacity to some extend.The content of polysaccharides in the ethanol extract of Laetiporus sulphureus was 117.08±5.46 mg/g.
