Grifola frondosa is marketed in China, Japan and other Asian countries as a medicinal and edible fungus. Several bioactive properties have been reported. This mushroom also has considerable levels of protein and its content may vary depending on culture conditions and the type of substrate used. In this study, we worked with dry and crushed fruit bodies of Grifola frondosa (HEMIM-43) cultivated on supplemented oak sawdust. Its proximal chemical composition, polyphenol content and inhibitory concentration (IC50) of an aqueous extract with ABTS and DPPH radicals were determined. Fruit bodies contained 28.9% protein, 2.4% ash, 6.8% ethereal extract, 44.8% nitrogen free extract and 17% fiber. The content of polyphenols was 0.26 mg GAE/g and antioxidant activity of ABTS and DPPH radicals was positively correlated with extract concentration. It is possible that fruit bodies contained substances that act as donors of hydrogen and react with free radicals to turn them into stable products and to complete the chain reaction.
