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.

Galloyl glucose
Galloyl glucose, also known as 1-galloyl-beta-D-glucose or beta-glucogallin, is a member of the class of compounds known as tannins. Tannins are naturally occurring polyphenols which be categorized into four main classes: hydrolyzable tannin (based on ellagic acid or gallic acid), condensed tannins (made of oligomeric or polymeric proanthocyanidins), complex tannins (made of a catechin bound to a gallotannin or elagitannin), and phlorotannins (oligomers of phloroglucinol). Galloyl glucose is soluble (in water) and a very weakly acidic compound (based on its pKa). Galloyl glucose can be found in a number of food items such as pomegranate, strawberry, redcurrant, and rubus (blackberry, raspberry), which makes galloyl glucose a potential biomarker for the consumption of these food products. Galloyl glucose is formed by a gallate 1-beta-glucosyltransferase (UDP-glucose: gallate glucosyltransferase), an enzyme performing the esterification of two substrates, UDP-glucose and gallate to yield two products, UDP and glucogallin. This enzyme can be found in oak leaf preparations .

6-O-Galloylglucose
6-o-galloylglucose is a member of the class of compounds known as galloyl esters. Galloyl esters are organic compounds that contain an ester derivative of 3,4,5-trihydroxybenzoic acid. 6-o-galloylglucose is soluble (in water) and a very weakly acidic compound (based on its pKa). 6-o-galloylglucose can be found in garden rhubarb, which makes 6-o-galloylglucose a potential biomarker for the consumption of this food product.
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 .
