Constituintes químicos de Parmotrema lichexanthonicum Eliasaro & Adler: isolamento, modificações estruturais e avaliação das atividades antibiótica e citotóxica Chemical constituents of parmotrema lichexanthonicum Eliasaro & Adler: isolation, structure modification and evaluation of antibiotic and cytotoxic activities

Química Nova, 2009
From the lichen Parmotrema lichexantonicum were isolated the depsidone salazinic acid, the xanthone lichexanthone, and the depside atranorin. The two major compounds, salazinic acid and lichexanthone, were selected for structure modifications.

Dereplicative Combination of HPLC/DAD/MS and 2D NMR to Identify Lichexanthone Isomers in Lichen Extracts

Phytochemical Analysis, Volume 37, Issue 2, Page 330-343, March 2026.
ABSTRACT Introduction Lichexanthones are the major xanthones found in lichens. They present a high degree of isomerism, which makes their identification tedious. Xanthones are known to occur in lichens according to chemosyndromes, and these compounds act as chemotaxonomic markers.

A New Lichen Depsidone from L Obaria Pulmonaria [PDF]

, 2012
The continuation of our phytochemical survey of Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), has led to the isolation and identification of a new lichen depsidone (1) characterised by the normal analytical and spectroscopic techniques. Unlike previously

Functional Traits Mediate Physico‐Chemical Niche Differentiation of Epiphytic Lichens and Bryophytes in Temperate Forests

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Host tree identity drives bark physico‐chemical filters (e.g., pH, metals) that shape epiphytic communities. We show that species‐specific functional traits, such as lichen substances and bryophyte growth forms, mediate these responses. Lichen metal homeostasis and bryophyte growth habit create distinct species thresholds and community change points ...
