RESUMO

The present study aims to assess the antioxidant activities (AOA) and total phenolic content (TPC) of water extracts of selected edible wild mushrooms: Pleurotus porrigens, Schizophyllum commune, Hygrocybe conica, and Lentinus ciliates. The AOA were evaluated against DPPH radical and ABTS radical cation scavenging ability, ferric-reducing antioxidant power (FRAP) and β-carotene-linoleate bleaching (β-CB) assays, and the Folin-Ciocalteu method for TPC. BHA was used as reference. P. porrigens showed significantly higher (p < 0.05) DPPH· scavenging ability (90.78 ± 0.30%) and FRAP (6.37 ± 0.22 mM FE/100g), while Sch. commune showed significantly higher (p < 0.05) ABTS·+ inhibition activity (94.96 ± 0.70%) and β-CB inhibition activity (94.18 ± 0.17%), respectively. TPC was found in a descending order of P. poriggens > L. ciliatus = Pleurotus ostreatus (cultivated) > H. conica = Sch. commune. Positive correlation was observed between the AOA and TPC. When compared to BHA (2 mM), P. porrigens showed significantly higher (p < 0.05) DPPH· scavenging ability and reducing power, while Sch. commune showed comparable DPPH· scavenging ability and ABTS·+ inhibition activity. All the mushrooms have better ABTS·+ inhibition activity than BHA (1 mM). The β-CB inhibition activity of BHA was significantly higher than those of edible wild mushrooms. The water extracts of edible wild mushrooms showed potent antioxidant activities compared to BHA to a certain extent.
