Phototoxic activity, Moraceae

Over 400 species of tropical plants from 76 families were assayed for phototoxic activity. Furanocoumarins, an important class of phototoxins, were identified from three genera of the Moraceae (fig family). Dorstenia. an herbaceous member of this family, was particularly rich in these metabolites. The distribution of furanocoumarins in the Moraceae as well as evolutionary and ecological aspects are discussed.
