Sažetak

This study is designed for the determination of proximate chemical composition, contents of bioactive compounds, and antioxidant activity of wild edible mushrooms Albarellus per-caprae and Armilaria mellea. The obtained results of chemical composition revealed that the mushrooms were rich source of proteins and carbohydrates, low in fat content, and provides a good source of energy. Concentrations of five bioactive compounds (ascorbic acid, β-carotene, lykopene, total phenols, and flavonoids) are determined in hot water and methanolic extracts of mushrooms fruit bodies. Three complementary chemical assays: reducing power, free radical scavenging (DPPH), and chelating ability for ferrous ions were used to screen the antioxidant properties of extracts. The highest antioxidant capacity values were found for hot water extracts of A. mellea (9.01 μM TE/g d.w. in reducing power, 65% in scavenging ability, and 85% in chelating ability). EC50 values for three different antioxidant assays were between 1.63 mg/mL to 6.86 mg/mL. Due to these characteristics, wild edible mushrooms A. per-caprae and A. mellea could be used in well-balanced diets and as a source of bioactive compounds.
