 One of the most common lichen substances is (+)-usnic acid, which occurs in high amounts in E.prunastri,​ but is not detected in Pseudevernia furfuracea (treemoss). It is possible to isolate >50g of pure usnic acid from 350 g of a resinoid, but the absolutes are practically free of it. \\ One of the most common lichen substances is (+)-usnic acid, which occurs in high amounts in E.prunastri,​ but is not detected in Pseudevernia furfuracea (treemoss).

-Methyl-β-orcinol carboxylate (10-20%, w/w of resinoid or extract) is the most important compound of the depsides and mono-aromatic compounds in oakmoss extracts. "​Although methyl β-orcinolcarboxylate was initially described as odourless, it became rapidly obvious that it is the major contributor to the odour of oakmoss extracts. Strangely enough, one had to wait until the middle of the 1960s to see a number of processes appear in the patent literature for the production of methyl-β-orcinol carboxylate and other structurally related artificial resorcylates with possible applications in fragrance formulations."​ \\+Methyl-β-orcinol carboxylate (10-20%, w/w of resinoid or absolute) is the most important compound of the depsides and mono-aromatic compounds in oakmoss extracts.
