In 1907, Wilhelm Zopf identified and classified about 150 lichen products. Seventy years later, this number had risen to 300, and by 1995, 850 lichen products were known; [8] as of 2021, more than 1000 have been identified. [9] Analytical methods were developed in the 1970s using thin-layer chromatography for the routine identification of ...
List of lichen products; Chemical spot tests on the foliose lichen Punctelia borreri showing thallus (top) and medulla (bottom). The pinkish-red colour change of the medulla in the C and KC tests indicate the presence of gyrophoric acid, a chemical feature that helps to distinguish this lichen from similar species in the same genus.

Thiophanic acid is a chlorine-containing xanthone compound first isolated from the lichen Lecanora rupicola in 1898. Its molecular structure, definitively established in 1966, consists of a xanthone core with four chlorine atoms and three hydroxyl groups, giving it the chemical formula C 14 H 6 Cl 4 O 5 .
Vulpinic acid is a natural product first found in and important in the symbiosis underlying the biology of lichens. [1] It is a simple methyl ester derivative of its parent compound, pulvinic acid, and a close relative of pulvinone, both of which derive from aromatic amino acids such as phenylalanine via secondary metabolism.
Chrysothrix chlorina, the sulphur dust lichen, is a species of leprose (powdery) crustose lichen in the family Chrysotrichaceae. [3] Originally described scientifically by the Swedish lichenologist Erik Acharius over 200 years ago, it has been shuffled to many different genera in its taxonomic history before finally being transferred to Chrysothrix in 1981.

Confluentic acid is a major lichen product in the crustose lichen Cryptothecia rubrocincta. [ 14 ] A study on Cryptothecia rubrocincta reveals distinct biochemical compositions in various parts of its thallus, suggesting specialised roles for the compounds present.
