The purpose of the presented investigation was to study the content of active metabolites in lichen species: Anaptychia ciliaris (L.) A. Massal, Flavoparmelia caperata (L.) Hale, Hypogymnia physodes (L.) Nyl., Parmelia sulcata Taylor, Peltigera canina (L.) Willd., Pseudevernia furfuracea (L.) Zopf. var. furfuracea, Ramalina farinacea (L.) Ach., Ramalina pollinaria (Westr.) Ach., Xanthoparmelia stenophylla (Ach.) Ahti & D. Hawksw growing in Georgia. The primary and secondary metabolites of

Spectrophotometrical and titration methods have been used for studies. Remarkably high content of carotenoids was discovered in Xanthoparmelia stenophylla compared to other tested species. Anaptychia ciliaris, Pseudovernia furfuracea and Ramalina farinacea were distinguished by the high content of chlorophylls, carotenoids and anthocyanins among the studied tree-inhabiting species. High content of proline was found in species: Xanthoparmelia stenophylla, Hypogymnia physodes, and Parmelia sulcata. Especially high content of phenols was determined in Peltigera canina. Ramalina pollinaria, Pseudovernia furfuracea, and Flavoparmelia caperata were distinguished by the high content of soluble carbohydrates, compared to other species. Content of total proteins was high in Ramalina farinacea, Pseudovernia furfuracea, and Flavoparmelia caperata. Hypogymnia physodes was distinguished by the high total antioxidant activity. Influence of the substrate on the quantitative characteristics of studied parameters was revealed. The same species of lichens may reveal different strategies of antioxidant defense a [...]
