Antioxidant status and selenium accumulation by 18 macromycetes species of the Mountainous Crimea was investigated. Total antioxidant activity of 5 families’ representatives composed ranges of 23.9 - 43.3 mg GAE/g d.w. for Boletaceae, 13.0-25.0 mg GAE/g d.w. for Russulaceae, 13.5-20.9 mg GAE/g d.w. for Tricholomotaceae, 13.8-38.0 mg GAE/g d.w. for Agaricaceae. Selenium accumulation levels reached 423-3352 µg/kg d.w. (Boletaceae), 236-1076 µg/kg d.w. (Russulaceae), 664-1213 µg/kg d.w (Tricholomotaceae) and 289-2392 µg/kg d.w. (Agaricaceae). High antioxidant activity (39.2 mg GAE/g d.w.) and specific carotenoid composition including 9-cis lycopene (1.8 mg/g) and beta-carotene (0.2 mg/g) were recorded for Clathrus ruber for the first time. The results indicate high significance of macromycetes investigated as powerful sources of antioxidants and selenium.
