“…Such groups of BAS as fatty acid derivatives, aldehydes and dienes, which were detected as a result of our study, were also found in the results of the previous studies of the raw material of C. islandica conducted by the GC/MS method [14]. However, these researchers did not mention the presence of terpenoids and their derivatives in the raw material studied.…”

The component composition and the quantitative content of compounds distilled with water vapor in the thalli of Cetraria islandica (L.) Ach. harvested in Ukraine were determined using the method of gas chromatography with mass spectrometric detection (GC/MS). 24 compounds distilled with water vapor were identified with the prevalence of fatty acids and their derivatives (57.86±2.00% of the total compounds), terpenoids and their derivatives (23.57±0.97% of the total compounds) and acyclic saturated hydrocarbons (10.99±0.45% of the total compounds). The highest percentage was observed for octadecadienoic (linoleic) acid (20.08±0.67% of the total compounds), hexadecanoic (palmitic) acid (19.21±0.77% of the total compounds) and 9,17-octadecadienal (18.57±0.56% of the total compounds). The presence of 4 monoterpenoids and 6 sesquiterpenoids in the raw material studied was determined for the first time.

“…Derivatives of methylbenzoic acids are commonly present in different genera of lichen-like Stereocaulon halei [ 51 ], Parmotrema mesotropum [ 52 ], Cassipourea malosana [ 53 ], Cetraria islandica [ 54 ], Usnea longissima [ 55 , 56 ], Stereocaulon paschale [ 57 ], and Parmelia sulcata Taylor [ 58 ]. Atraric acid ( Figure 2 ), widely present in some species such as Hypogymnia physodes , Evernia prunastri , and Parmelia sulcata , growing on the same host tree ( Prunus domestica ) [ 59 ], can be in the free or complexed form and serves as a basis for the composition of depsides and depsidones [ 60 ].…”

Phytochemical Investigation of New Algerian Lichen Species: Physcia Mediterranea Nimis

et al. 2021

The present study provides new data concerning the chemical characterisation of Physcia mediterranea Nimis, a rare Mediterranean species belonging to the family Physciaceae. The phytochemical screening was carried out using GC-MS, HPLC-ESI-MS-MS, and NMR techniques. Hot extraction of n-hexane was carried out, followed by separation of the part insoluble in methanol: wax (WA-hex), from the part soluble in methanol (ME-hex). GC-MS analysis of the ME-hex part revealed the presence of methylbenzoic acids such as sparassol and atraric acid and a diterpene with a kaurene skeleton which has never been detected before in lichen species. Out of all the compounds identified by HPLC-ESI-MS-MS, sixteen compounds are common between WA-hex and ME-hex. Most are aliphatic fatty acids, phenolic compounds and depsides. The wax part is characterised by the presence of atranorin, a depside of high biological value. Proton 1H and carbon 13C NMR have confirmed its identification. Atranol, chloroatranol (depsides compound), Ffukinanolide (sesquiterpene lactones), leprolomin (diphenyl ether), muronic acid (triterpenes), and ursolic acid (triterpenes) have also been identified in ME-hex. The results suggested that Physcia mediterranea Nimis is a valuable source of bioactive compounds that could be useful for several applications as functional foods, cosmetics, and pharmaceuticals.

“…This species is commonly known as true Iceland lichen or Iceland moss. C. islandica is used in treating and prophylaxis of chronic obstructive pulmonary disease (COPD), mainly tuberculosis [9]. C. islandica is also used in the food industry as an additive in sweet dishes [10], and traditionally it is used for preparing herbal tea and homemade decoctions for treating dry cough, a temporary loss of appetite, and oral mucosal problems [11].…”

The lichen Cetraria islandica (L.) Ach. has been used in traditional and modern medicines for its many biological properties such as immunological, immunomodulating, antioxidant, antimicrobial, and anti-inflammatory activities. This species is gaining popularity in the market, with interest from many industries for selling as medicines, dietary supplements, and daily herbal drinks. This study profiled the morpho-anatomical features by light, fluorescence, and scanning electron microscopy; conducted an elemental analysis using energy-dispersive X-ray spectroscopy; and phytochemical analysis was performed using high-resolution mass spectrometry combined with a liquid chromatography system (LC-DAD-QToF) of C. islandica. In total, 37 compounds were identified and characterized based on comparisons with the literature data, retention times, and their mass fragmentation mechanism/s. The identified compounds were classified under five different classes, i.e., depsidones, depsides, dibenzofurans, aliphatic acids, and others that contain simple organic acids in majority. Two major compounds (fumaroprotocetraric acid and cetraric acid) were identified in the aqueous ethanolic and ethanolic extracts of C. islandica lichen. This detailed morpho-anatomical, EDS spectroscopy, and the developed LC-DAD-QToF approach for C. islandica will be important for correct species identification and can serve as a useful tool for taxonomical validation and chemical characterization. Additionally, chemical study of the extract of C. islandica led to isolation and structural elucidation of nine compounds, namely cetraric acid (1), 9′-(O-methyl)protocetraric acid (2), usnic acid (3), ergosterol peroxide (4), oleic acid (5), palmitic acid (6), stearic acid (7), sucrose (8), and arabinitol (9).
