Abstract:
From time immemorial, mushrooms have been valued by humankind as a culinary wonder and folk medicine. Recently, it has been discovered that many fungal species, represent miniature pharmaceutical factories producing hundreds of natural compounds which possess a broad-range of potent bioactivities . The aim of this work was to study anti-DPPH radical activity and ferric reducing potential (FRAP) of crude ethanol (AMEtOH) and water extracts (AMAq) of wild-growing fungal species Armillaria mellea, collected in Eastern Serbia (Sikole, near Negotin), in relation to total phenolic content measured colorimetrically by the Folin – Ciocalteu assay. The highest anti-DPPH radical activity and ferric reducing potential was observed for AMAq (IC50 36.77µg/ml and 21.15 mg AAEq/g d.w., respectively). In addition, total phenolic content (TP) was highest in AMAq (82.926 mg GAE/g d.w.) and the correlations obtained between anti-DPPH radical activity and total phenolic content (r2 = 0.85) indicated that the presence of phenolic compounds is potentially responsible for the observed activities. In conclusion, the selected fungal species may actually inspire further experiments with antioxidant design, aiming to offer powerful antioxidants with a broad range of use.
