Parietin
Physcion is a dihydroxyanthraquinone that is 9,10-anthraquinone bearing hydroxy substituents at positions 1 and 8, a methoxy group at position 3, and a methyl group at position 6. It has been widely isolated and characterised from both terrestrial and marine sources. It has a role as an apoptosis inducer, an antineoplastic agent, a hepatoprotective agent, an anti-inflammatory agent, an antibacterial agent, an antifungal agent and a metabolite. It is functionally related to a 2-methylanthraquinone. Physcion is a natural product found in Rumex dentatus, Ageratina altissima, and other organisms with data available.

physcion
Physcion, also known as emodin monomethyl ether or parienin, is a member of the class of compounds known as anthraquinones. Anthraquinones are organic compounds containing either anthracene-9,10-quinone, 1,4-anthraquinone, or 1,2-anthraquinone. Physcion is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Physcion can be synthesized from 2-methylanthraquinone. Physcion can also be synthesized into torososide B and physcion 8-gentiobioside. Physcion can be found in common sage, garden rhubarb, and sorrel, which makes physcion a potential biomarker for the consumption of these food products. Physcion 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 .
