摘要: Abstract The antioxidant activities of two homogeneous polysaccharides, water extraction polysaccharide (W-PTR) and alkali (A-PTR) from Pleurotus tuber-regium (Fr.) Sing. were evaluated. Results showed that W-PTR was stronger than A-PTR in O 2 - scavenging activity, while the to OH, DPPH , inhibition effects on liver lipid peroxidation, mitochondria swelling, red blood cell (RBC) hemolysis. At concentration 0.3 g/L, activity 85.7% 71.7%. 0.25 g/L, OH 64.20% 74.97%. peroxidation 79.37%. 0.8 g/L, hemolysis rate 77.16%. polysaccharides P. had strong potency might be exploited as effective natural alleviate oxidative stress.
