ABSTRACT

Several fractions derived from culinary—medicinal Pleurotus abalonus by ethanol precipitation and chromatography on DEAE/cellulose were investigated for their antioxidant activity in two assays—namely, inhibition of hemolysis of rat erythrocyte induced by peroxyl radicals and inhibition of lipid peroxidation of rat brain homogenate. Total phenolics, polysaccharide, and protein contents of these fractions were determined. Positive correlations were found between total phenolic content of fractions and their antioxidant activities. P. abalonus may have potential as a natural antioxidant.
