Abstract
Seven mols. isolated from lichen species were tested as antioxidants and photoprotectors of UV-B (280-315 nm.) radiation. Perlatolic acid was the best of these seven mols. The decarboxythamnolic, usnic and usnic acid deriv. showed activity as photoprotectors. Finally, thamnolic acid showed good scavenging activity.
