Lichens: Might be considered as a source of gastroprotective molecules?
(Sociedad Chilena de Quimica, 2013)
Lichens are symbiotic relationship between fungi and algae or cyanobacteria. Secondary metabolites from lichens are known as lichen substances. We investigated depsidone and depside from lichens 1-6 in the context of their ...

Production of the bioactive pigment elsinochrome A by a cultured mycobiont strain of the lichen Graphis elongata
(Springer Heidelberg, 2018-04)
We report the production of the perylenequinone pigment elsinochrome A in aposymbiotic culture of the mycobiont of the crustose epiphytic lichen Graphis elongata Zenker (Lecanoromycetes), collected in Argentina (Buenos ...
Are Ionic Liquids Better Extracting Agents Than Toxic Volatile Organic Solvents? A Combination of Ionic Liquids, Microwave and LC/MS/MS, Applied to the LichenStereocaulon glareosum
(Frontiers Media, 2020)
We report a green strategy for the extraction of lichen substances fromStereocaulon glareosum. This sustainable alternative does not use volatile toxic organic solvents, but it is assisted by microwave and is checked by ...
Intrinsic factors of Peltigera lichens influence the structure of the associated soil bacterial microbiota
(Oxford University Press, 2016)
Definition of lichens has evolved from bi(tri)partite associations to multi-species symbioses, where bacteria would play essential roles. Besides, although soil bacterial communities are known to be affected by edaphic ...
Antimycobacterial activity of lichen substances
(Elsevier Gmbh, Urban & Fischer Verlag, 2010-04-01)
We describe here the extraction and identification of several classes of phenolic compounds from the lichens Parmotrema dilatatum (Vain.) Hale, Parmotrema tinctorum (Nyl.) Hale, Pseudoparmelia sphaerospora (Nyl.) Hale and ...

Pseudocyphellae ontogeny and thallus anatomy in species of Punctelia Krog (Parmeliaceae, lichenized Ascomycota)
(Soc Botanica Brasil, 2017-01-01)
The genus Punctelia has been traditionally characterized by the type and distribution of pseudocyphellae, medullary chemical substances and the shape of conidia, whereas its species have been distinguished using mainly the ...
