Lichenochemical Screening and Antioxidant Capacity of Four Tunisian Lichen Species

The phenolic composition and antioxidant capacity of four Tunisian lichen species, Cladonia rangiformis , Flavoparmelia caperata , Squamarina cartilaginea and Xanthoria parietina , were determined in order to provide a better understanding of their lichenochemical composition. Powdered material of F. caperata was the richest in total phenolic content (956.68 μg GAE g −1 DW) and S. cartilaginea in proanthocyanidin content (77.31 μg CE g −1 DW),...
