Clavaria mushrooms and extracts: Investigation on valuable components and antioxidant properties

Abstract

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. A 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.
