Secondary metabolites of lichens in the snow zone of the Sierra Nevada in Mérida-Venezuela and their role in the absorption of ultraviolet radiation

Anales del Jardín Botánico de Madrid, 2008
Photochemical analyses of secondary compounds in lichens from the venezuelan andean snow zone were carried out in order to know the absorbance capacity of UV radiation at the UVA, UVB and UVC ranges and to determine its probable UV protective function ...

A new depsidone of Lobaria pulmonaria with acetylcholinesterase inhibition activity

Journal of Enzyme Inhibition and Medicinal Chemistry, 2012
The phytochemical investigation conducted on a foliose lichen, Lobaria pulmonaria(L.) Hoffm. (Lobariaceae), led to the isolation of a new depsidone in the form of its diacetate derivative which showed a moderate acetylcholinesterase inhibition activity (1 µg) in vitro.
