Chemical compounds and antioxidant activity of Antarctic lichens
Abstract We assessed the content of some major and trace elements and lichen compounds as well as antioxidant activity in eight lichen species representing four families collected in areas > 1 km distant from Bellingshausen (King George Island) and > 1 km distant from Molodezhnaya (Thala Hills...
