Chemical Information
FooDB NameIsopimpinellin
DescriptionIsopimpinellin, also known as dimethylpsoralen, belongs to the class of organic compounds known as 8-methoxypsoralens. These are psoralens containing a methoxy group attached at the C8 position of the psoralen group. Isopimpinellin is an extremely weak basic (essentially neutral) compound (based on its pKa). Isopimpinellin is found, on average, in the highest concentration within a few different foods, such as parsley, celery stalks, and fennels. Isopimpinellin has also been detected, but not quantified in, several different foods, such as wild celeries, carrots, parsnips, lemons, and angelica. This could make isopimpinellin a potential biomarker for the consumption of these foods. Isopimpinellin is a potentially toxic compound.
