What it is Filled
A class of organic compounds formed by a furan ring fused to a coumarin, produced by plants such as citrus, celery, parsnip and giant hogweed as defence chemicals, including psoralen, bergapten and xanthotoxin and many natural derivatives; furanocoumarins cause phytophotodermatitis when skin exposed to them meets sunlight, are responsible for grapefruit interactions with many drugs by inhibiting intestinal enzymes, and are used in controlled phototherapy for skin conditions.
Why it exists Filled
Let an agent explain furanocoumarins and their chemistry and plant sources, describe their effects on skin and drug metabolism in general terms, relay safety information from health bodies, and route personal medical questions to professionals.
Distinguishing features Filled
- Phototoxicity
- Grapefruit drug interaction
- Plant defence
- Phototherapy use
What robots and AI may and may not do Filled
Must not
- Advise touching or cutting plants rich in furanocoumarins without protection.
- Dismiss interactions between grapefruit and medicines.
- Help use these compounds to harm people.
Only with a human decision
- Changing a patient's medication because of a dietary interaction.
May
- Explain furanocoumarins, their sources and effects, such as interactions with medicines.
- Warn people handling plants such as giant hogweed about skin reactions in sunlight.
Moral aspects Filled
- Contact with some plants causes severe burns, often in children.
- Food-drug interactions can be dangerous and poorly known.
Who is affected
- Children and gardeners
- Patients on medication

Identity and identifiers required Filled
- Vercy registry: vr.tr.furanocoumarin
- Wikidata: Q414774 (https://www.wikidata.org/wiki/Q414774)
Direct properties required Filled
- Molar mass: g/mol - Calculate the value from the molecular formula of the identified furanocoumarin because substitutions vary across the class.
- Melting temperature: degrees Celsius - Measure the identified compound by thermal analysis or a melting point method while recording purity and any decomposition.
- Solubility: g/L - Measure the equilibrium dissolved concentration for the specified compound, solvent and temperature.
- Ultraviolet absorption wavelength: nm - Determine absorption maxima by ultraviolet-visible spectroscopy with the compound and solvent identified.
Recognition required Filled
- Furan ring fused to coumarin
- Citrus, celery, parsnip, hogweed
- Simple coumarins lack the furan ring; flavonoids are a different class
- Not physical; molecules.
Capabilities and actions required Filled
- explain chemistry and sources
- describe effects generally
- relay safety information
- route personal questions
Hazards and failure modes required Filled
- Skin burns from plant contact and sun
- Drug interactions from grapefruit
- Agents giving personal medical advice
Standards and interfaces required Filled
- Drug labelling on grapefruit interactions
- Cosmetic ingredient restrictions
- Phototherapy clinical guidelines
Context of use required Filled
- Furan-fused coumarin plant compounds.
- linear furanocoumarins such as psoralen
- angular furanocoumarins
- citrus furanocoumarins
- furanocoumarins in Apiaceae plants
- derivatives from other plant families
