Lichens produce different classes of phenolic compounds, including anthraquinones,
xanthones, dibenzofuranes, depsides and depsidones. Many of them have revealed …

Lichens are symbiotic associations between fungi and a photosynthetic alga and/or
cyanobacteria. Lichenized fungi have been found to produce a wide array of secondary …

Lichens are complex symbiotic associations between fungi and algae which are important
constituents of many ecosystems. The production of various unique extracellular secondary …

Ethnopharmacological relevance Lichens, a unique symbiotic association between an
alga/cyanobacterium and a fungus, produce secondary metabolites that are a promising …

Lichens present a symbiotic association between two or more organisms. These unique
organisms produce many chemical compounds, known as secondary metabolites or lichen …

Context: Lichens are composite organisms consisting of a symbiotic association of a fungus
(the mycobiont) with a photosynthetic partner (the phytobiont), usually either a green alga or …

Lichens represent unique symbiosis of fungi (mycobionts) and algae (photobionts). Living in
extreme conditions they developed various compounds to survive. Many of these original …

Biological activity of material whether known in folk medicine or observed in planned
screening program has been the starting point in the drug research. The general pattern is …

Secondary metabolites present in lichens, which comprise aliphatic, cycloaliphatic, aromatic
and terpenic compounds, are unique with respect to those of higher plants and show …

The purpose of this study was to investigate the effects of six lichen metabolites (diffractaic
acid, lobaric acid, usnic acid, vicanicin, variolaric acid, protolichesterinic acid) on …
