| "... the fragrance industry indiscriminately indicated under the name of ‘oakmoss’ the lichen collected on oak trees or the lichen collected on other trees. However, distinction has been made traditionally between ‘cedarmoss’ collected mainly in Morocco on cedar trees (Cedrus atlantica), and ‘treemoss’ gathered from pine trees (Pinus spp.), although the lichen species is actually the same (P. furfuracea). The difference in fragrance is mainly attributable to the wood, twigs, bark, etc. from pine trees, which contaminate the lichen to various extents... \\ | "... the fragrance industry indiscriminately indicated under the name of ‘oakmoss’ the lichen collected on oak trees or the lichen collected on other trees.

| In principle, so-called treemoss extracts are mostly manufactured from Pseudevernia furfuracea (L.) Zopf., a lichen which is particularly common on coniferous trees, mainly pine, and cedar trees. Four chemical races of P. furfuracea have been defined: one contains mainly physodic acid, a second physodic and olivetoric acids, a third olivetoric acid and the last one physodic, olivetoric and oxyphysodic acids... \\ | In principle, so-called treemoss extracts are mostly manufactured from Pseudevernia furfuracea (L.)

| - | The content of defined lichen compounds in P. furfuracea has only rarely been measured. In most cases, the preferred analytical technique is HPLC. For example, atranorin, physodic acid, hydroxyphysodic acid and virensic acid are claimed to represent 0.11–0.19%, 1.46–3.78%, 1.69–3.44% and 1.14–1.46%, respectively, | + | The content of defined lichen compounds in P. furfuracea has only rarely been measured.
