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.

Sterigmatocystin
Sterigmatocystin is a mycotoxin of Aspergillus versicolor and Chaetomium species Sterigmatocystin is a poison of the type dermatoxin, from the fungi genus Aspergillus. It appears on crusts of cheese with mold. Sterigmatocystin is a toxic metabolite structurally closely related to the aflatoxins (compare general fact sheet number 2), and consists of a xanthone nucleus attached to a bifuran structure. Sterigmatocystin is mainly produced by the fungi Aspergillus nidulans and A. versicolor. It has been reported in mouldy grain, green coffee beans and cheese although information on its occurrence in foods is limited. It appears to occur much less frequently than the aflatoxins, although analytical methods for its determination have not been as sensitive until recently, and so it is possible that small concentrations in food commodities may not always have been detected. Although it is a potent liver carcinogen similar to aflatoxin B1, current knowledge suggests that it is nowhere near as widespread in its occurrence. If this is the true situation it would be justified to consider sterigmatocystin as no more than a risk to consumers in special or unusual circumstances. Sterigmatocystin is a number of closely related compounds such o-methyl sterigmatocystin are known and some may also occur naturally. The IARC-classification of sterigmatocystin is group 2B, which means it is possibly carcinogenic to humans. In practice, the risk is quite low however, because this substance only appears on cheese crusts with mold, and because of that the chance of daily exposure is very low. Sterigmatocystin is a molded crust is best not to be consumed in whole, but after removing the crust, the cheese can still be consumed. Sterigmatocystin is a different kind of mold than that which appears on cheese itself, which can simply be removed before further consumption D009676 - Noxae > D011042 - Poisons > D009183 - Mycotoxins CONFIDENCE Reference Standard (Level 1); INTERNAL_ID 2320

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 .
Erythroglaucin
A trihydroxyanthraquinone that is anthracene-9,10-dione substituted by hydroxy groups at positions 1, 4 and 5, a methoxy group at position 7 and a methyl group at position 2. It has been isolated from Chaetomium globosum and other fungal species.

Isotetrahydroauroglaucin
A member of the class of benzaldehydes that is benzaldehyde substituted by hydroxy groups at positions 3 and 6, a prenyl group at position 5 and a a hept-5-en-1-yl at position 2. Isolated from Chaetomium globosum and other fungal species, it exhibits radical scavenging activities.
Sterigmatocystin
An organic heteropentacyclic compound whose skeleton comprises a xanthene ring system ortho-fused to a dihydrofuranofuran moiety. The parent of the class of sterigmatocystins. D009676 - Noxae > D011042 - Poisons > D009183 - Mycotoxins CONFIDENCE Reference Standard (Level 1)
