Literature References: One of a group of furocoumarins occurring naturally in more than two dozen plant sources, including Rutaceae (e.g. bergamot, limes, cloves), Umbelliferae (e.g. celery, parsnips), Leguminosae (e.g. Psoralen coryfolia), and Moraceae (e.g. figs).

Chem. 111, 877 (1980). Psoralens are phytoalexins; they are used by plants in a defensive response to attacks by fungi and insects: M. Berenbaum, P. Feeny, Science 212, 927 (1981). They have also shown photosensitizing and phototoxic effects in animals and humans and have been used in photochemotherapy for management of vitiligo, psoriasis, and mycosis fungoides, cf. T. F. Anderson, J. J. Voorhees, Annu. Rev. Pharmacol. Toxicol. 20, 235 (1980); A. Kornhauser et al., Science 217, 733 (1982). Review of psoralen photochemistry: B. J. Parsons, Photochem.
