文摘

Fresh picked and herbarium thalli of Cladonia stellaris, C. rangiferina, Allocetraria nivalis, A. cucullata, Cetraria islandica, Peltigera canina, and Nephroma articum epigene lichens were studied using the immune-enzyme analysis. No big difference was observed in the contents of mycotoxin secondary metabolites, i.e., deoxynivalenol, diacetoxyscirpenol, zearalenone, alternariol, citrinin, sterigmatocystin, cyclopiazonic acid, mycophenolic acid, emodin, and PR-toxin. The discovery of these substances in the specimens preserved for several decades shows that lichens have an effective system of conservation of metabolic exchange products.
