About: Parietin

An Entity of Type: chemical substance, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Parietin is the predominant cortical pigment of lichens in the genus Caloplaca, a secondary product of the lichen Xanthoria parietina, and a pigment found in the roots of Curled Dock (Rumex crispus). It has an orangy-yellow color and absorbs blue light. It is also known as physcion. It has also shown anti-fungal activity against and , more efficiently in the latter case than treatments with fenarimol and . It reacts with KOH to form a deep, reddish-magenta compound.

  • Parietin is the predominant cortical pigment of lichens in the genus Caloplaca, a secondary product of the lichen Xanthoria parietina, and a pigment found in the roots of Curled Dock (Rumex crispus). It has an orangy-yellow color and absorbs blue light. It is also known as physcion. It has also been shown to protect lichens against UV-B light, at high altitudes in Alpine regions. The UV-B light stimulates production of parietin and the parietin protects the lichens from damage. Lichens in arctic regions such as Svarlbard retain this capability though they do not encounter damaging levels of UV-B, a capability that could help protect the lichens in case of Ozone layer thinning. It has also shown anti-fungal activity against and , more efficiently in the latter case than treatments with fenarimol and . It reacts with KOH to form a deep, reddish-magenta compound. (en)
  • La pariétine, appelée aussi physcion, est le pigment cortical de couleur jaune/orange appartenant à la famille des anthraquinones. C'est le pigment principal des lichens du genre Xanthoria et Caloplaca : il s'y dépose en cristaux extracellulaires dans leur cortex supérieur. On le retrouve aussi dans les racines de Rumex crispus. Le thalle de ces lichens est K+ rouge-pourpre (réaction de la pariétine avec la KOH). (fr)
