[Secondary fungal metabolites (mycotoxins) in lichens of different taxonomic groups].
Secondary fungal metabolites (mycotoxins) in 22 lichen species of the families Parmeliaceae, Nephromataceae, Umbilicariaceae, Ramalinaceae, Cladoniaceae, Peltigeraceae, and Teloschistaceae were identified determined by enzyme immunoassay enzyme-linked immunosorbent assay. The following mycotoxins were identified found in these lichens in a broad concentration range with a frequency of 70-100%: sterigmatocystin (7-2090 ng/g), alternariol (20-6460 ng/g), and emodin (45-94500 ng/g). Mycophenolic acid frequently occurred in 19 lichen species; citrinin, in 17 species; diacetoxyscirpenol, in 11 species; cyclopiazonic acid, in 10 species; and zearalenone, in 9 species. PR toxin was regularly detected in three lichen species; deoxynivalenol, fumonisins, and ochratoxin A, in two species; and T-2 toxin and ergot alkaloids, in one species. Aflatoxin B1 was detected in only six species with a frequency of 2-42%, whereas roridin A was identified present in 10% of Hypogymnia physodes samples.
