Abstract
The superoxide and hydroxyl radical scavenging activities of eight mushroom antitumor polysaccharide extracts were investigated using phenazin methosulphate-NADH-nitroblue tetrazolium system and ascorbic acid-Cu(2+)-cytochrome C system respectively. The results showed that six of eight mushroom polysaccharide extracts had superoxide and hydroxyl radical scavenging activities. The protein content of the polysaccharide extracts appeared to contribute a direct effect on free radical scavenging activity. However, none of the mushroom polysaccharide extracts had antioxidative activity as measured by detecting malondialdehyde (MDA) contents of liver microsomes.Entities:
