Sažetak
Two Clavaria mushrooms were investigated as sources of antioxidant compounds, essential trace elements Selenium and Zinc, and as efficient antioxidants in elimination/inhibition of different radical species. Using HPLC method, pistillarin - rare siderphore compound characterized with high antioxidant activity, was detected in both extracts. Higher content of pistillarin has been measured in C. pistillaris extract. The same extract contained the higher content of Selenium, 3.051 μg/g. Both extracts showed important antioxidant activity. For C. pistillaris extract lower IC50 value has been measured and higher antioxidant activity against O2˙- radical has been detected. Although the content of pistillarin was higher in the case of C. pistillaris, at the concentration of 0.2 mg/ml C. fennica extract showed just some higher antioxidant activity against ˙OH radicals, 82% and 87%, respectively.
