Metabolite Identification
Common NameImperatorin
DescriptionImperatorin, also known as ammidin or marmelosin, belongs to the class of organic compounds known as psoralens. These are organic compounds containing a psoralen moiety, which consists of a furan fused to a chromenone to for 7H-furo[3,2-g]chromen-7-one. Imperatorin is found, on average, in the highest concentration within a few different foods, such as parsnips (Pastinaca sativa), lovages (Levisticum officinale), and parsleys (Petroselinum crispum) and in a lower concentration in fennels (Foeniculum vulgare). Imperatorin has also been detected, but not quantified in, several different foods, such as lemons (Citrus limon), root vegetables, anises (Pimpinella anisum), lambsquarters (Chenopodium album), and wild celeries (Apium graveolens). This could make imperatorin a potential biomarker for the consumption of these foods. Imperatorin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Imperatorin.
