A naturally occurring furocoumarin, found in PSORALEA. After photoactivation with UV radiation, it binds DNA via single and double-stranded cross-linking. Found in common vegetables, e.g. parsnip, celery esp. if diseased or `spoiled' Psoralen is a significant mutagen and is used for this purpose in molecular biology research.

Psoralen is found in carrot. Psoralen is found in common vegetables, e.g. parsnip, celery especially if diseased or `spoiled' Psoralen is a significant mutagen and is used for this purpose in molecular biology research. Psoralen has been shown to exhibit anti-proliferative, anti-allergenic and anti-histamine functions (A7781, A7782, A7782). Psoralen belongs to the family of Furanocoumarins. These are polycyclic aromatic compounds containing a furan ring fused to a coumarin moeity.
