| Resumen en inglés | Coumarins are special metabolites well distributed in the Angiospermae, either in Monocotyledoneae or Dicotyledoneae. Simple coumarins, the most widespread type, is found in all coumarin-producing families, such as: Apiaceae, Rutaceae, Asteraceae, Fabaceae, Oleaceae, Moraceae e Thymelaeaceae. The other types, linear- and angular furanocoumarins, linear- and angular pyranocoumarins, lignocoumarins, bis- and triscoumarins, are of more restricted circumscription. Among the families with occurrence numbers (NO) > 100, the more advanced ones are specialized in the production of only one or two coumarin types, while the primitive families are very well diversified in types. Calculations of percentual numbers of occurrence (%NO) show relevant meaning of coumarin-types in the taxonomic positioning of the producing taxa |
