Metabolite Identification

Common Name

Rhein

Description

Rhein belongs to the class of organic compounds known as anthracenecarboxylic acids. These are organic compounds containing a carboxylic acid group attached to an anthracene ring system. Thus, rhein is considered to be an aromatic polyketide. Rhein has been detected, but not quantified in, a few different foods, such as docks (Rumex), garden rhubarbs (Rheum rhabarbarum), and green vegetables. This could make rhein a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Rhein.
