The chemistry of Pseudocyphellaria impressa S. Lat. in New Zealand [PDF]
, 1979 As part of a detailed study of the nomenclature and taxonomy of the New Zealand species of Pseudocyphellaria it has been noted that the chemistry of the P. impressa (Hook & Taylor) Vainio aggregate, that is species with a markedly faveolate (honeycomb-

Marine Drugs, 2022 One new depsidone derivative, aspergillusidone H (3), along with seven known biosynthetically related chlorinated polyketides, were obtained from the Beibu Gulf coral-derived fungus Aspergillus unguis GXIMD 02505.

How to build a lichen: from metabolite release to symbiotic interplay
New Phytologist, Volume 238, Issue 4, Page 1362-1378, May 2023., 2023 Summary Exposing their vegetative bodies to the light, lichens are outstanding amongst other fungal symbioses. Not requiring a pre‐established host, ‘lichenized fungi’ build an entirely new structure together with microbial photosynthetic partners that neither can form alone.

Antigenotoxicity of Depsidones Isolated from Brazilian Lichens
Orbital: The Electronic Journal of Chemistry, 2017 Although phenolic compounds produced by lichens have been widely investigated in antitumor assays, only a small number have been evaluated for mutagenicity and genotoxicity.

Two‐step isolation of the two major paraconic acids of Cetraria islandica
Journal of Separation Science, Volume 46, Issue 6, March 2023., 2023 The lichen Cetraria islandica is traditionally used as a demulcent for the symptomatic treatment of irritations of the mouth and throat and associated dry cough, as well as for the treatment of temporary loss of appetite. In addition to depsides and depsidones, thalli contain paraconic acids, a group of secondary metabolites commonly found in lichens ...

ASAP‐MS and DART‐MS as ancillary tools for direct analysis of the lichen metabolome
Phytochemical Analysis, Volume 33, Issue 7, Page 1028-1035, October 2022., 2022 Abstract Introduction Lichens contain unique metabolites that most often need to be characterized from a limited amount of material. While thin layer chromatography is still the preferred analysis method for most lichenologists, liquid chromatography gives a deeper insight in the lichen metabolome, but an extractive step is needed before any analysis ...

Phytochemical Analysis, Volume 33, Issue 7, Page 1111-1120, October 2022., 2022 Abstract Introduction In recent years, LC‐MS has become the golden standard for metabolomic studies. Indeed, LC is relatively easy to couple with the soft electrospray ionization. As a consequence, many tools have been developed for the structural annotation of tandem mass spectra.

Anti‐Inflammatory Potential of Compounds Isolated from Tunisian Lichens Species
Chemistry &Biodiversity, Volume 19, Issue 8, August 2022., 2022 Abstract The lichen's special symbiotic structure enables it to produce bioactive substances. They have historically been recognized for their aesthetic and medicinal benefits. Furthermore, in recent years, they have performed in various fields, including perfumery, dyeing, and pharmacology due to their rich secondary metabolites.

Ecosphere, Volume 13, Issue 4, April 2022., 2022 Abstract We propose that a qualitative trait approach based on more detailed nuanced traits may reveal previously overlooked patterns, especially when combined with phylogenetic perspectives. By sampling epiphytic lichens and using a functional approach based on nuanced qualitative traits, such as a much greater resolution over photobiont identity ...

Chemical properties of key metabolites determine the global distribution of lichens
Ecology Letters, Volume 25, Issue 2, Page 416-426, February 2022., 2022 In lichen symbioses, secondary metabolites produced by the lichen fungi (mycobionts) provide UV protection on which trebouxioid green algae as the most prominent photobionts sensitively depend. These metabolites differ in their UV absorbance capability and solvability and therefore vary in their propensity of being leached from the lichen body by high ...
