The lichen-forming fungi Cetraria islandica has been largely used in folk medicines, and it has recently showed promising in vitro antioxidant effects in glial-like cells. Current work aimed at investigating the neuroprotective potential of its major isolated secondary metabolite: the depsidone fumarprotocetraric acid (FUM).

The biosynthesis of the depsidone, fumarprotocetraric acid, a compound previously considered to be only produced by lichens, has been confirmed by using alginate-immobilized cells of Cladonia verticillaris. Immobilized cells only produce the depsidone when they are supplemented with FMN and acetate.

The FT-Raman and infrared vibrational spectra of some important lichen compounds from two metabolic pathways are characterised. Key biomolecular marker bands have been suggested for the spectroscopic identification of atranorin, gyrophoric acid, fumarprotocetraric acid rhizocarpic acid, calycin, pulvinic dilactone and usnic acid.

The lichen Cladonia verticillaris produces bioactive secondary metabolites, such as fumarprotocetraric (FUM) and protocetraric acids. Species of the genus Cladonia demonstrate anti-tumor, anti-inflammatory and antipyretic activities and have been used in folk medicine to treat respiratory diseases (throat irritation, cough, asthma and tuberculosis ...

In the Cladonia chlorophaea group in North Carolina, consisting of six sibling species characterized by natural-product chemistry, three species produce fumarprotocetraric acid as a constant constituent and two species as an accessory substance. Fumarprotocetraric acid production in the species group as a whole decreases from the Mountains through the ...

Abstract A quantitative reversed-phase HPLC method for the analysis of protolichesterinic- and fumarprotocetraric acids in Cetraria islandica (L.) Ach. is described. The compounds were extracted from dry plant material with acetone. HPLC analysis was performed using a LiChrosorb RP-8 column, isocratic elution and UV detection.
