Description

Physcion, also known as parienin or rheochrysidin, belongs to the class of organic compounds known as anthraquinones. These are organic compounds containing either anthracene-9,10-quinone, 1,4-anthraquinone, or 1,2-anthraquinone. Physcion is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Physcion has been detected, but not quantified in, a few different foods, such as common sages, garden rhubarbs, and sorrels. This could make physcion a potential biomarker for the consumption of these foods. parietin was first documented in 2006 (PMID: 17125234). 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 (PMID: 17397111).
