Chemical Information
FooDB 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 an extremely weak basic (essentially neutral) compound (based on its pKa). Imperatorin is found, on average, in the highest concentration within a few different foods, such as parsnips, lovages, and parsley and in a lower concentration in fennels. Imperatorin has also been detected, but not quantified in, several different foods, such as lambsquarters, dills, limes, fruits, and lemons. This could make imperatorin a potential biomarker for the consumption of these foods. Imperatorin is a potentially toxic compound.
