What it is Filled

Diosmetin is a naturally occurring O-methylated flavone, specifically 3',5,7-trihydroxy-4'-methoxyflavone, that forms the aglycone of the flavonoid glycoside diosmin.

In scope

  • Molecular identity, substitution pattern and identifier reconciliation
  • Sample purity, related compounds, residual solvents and water content
  • Solid form, solution behaviour and condition-dependent physical measurements
  • Preparation provenance, storage history and analytical traceability
  • Evidence supporting handling decisions and research suitability

Out of scope

  • Diosmin and other diosmetin glycosides as independent substances
  • Plant species and extracts containing diosmetin
  • Finished medicines, supplements and formulated products
  • Manufacturing processes and laboratory equipment as independent models
  • Clinical treatment protocols, dosing recommendations and disease models

Why it exists Filled

Enable an agent to recognise diosmetin, assess the identity and condition of a particular sample, and determine its suitability for a documented analytical or research use.

Distinguishing features Filled

  • Require the flavone structure with hydroxyl groups at 5, 7 and 3' and a methoxy group at 4'; diosmetin is luteolin's 4'-O-methyl ether. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Diosmetin)
  • Reconcile the proposed identity with molecular formula C16H12O6, CAS 520-34-3 and PubChem CID 5281612; matching a name alone is insufficient. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Diosmetin)
  • Distinguish the free aglycone from diosmin or another glycoside by establishing whether a sugar substituent is present. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Diosmetin)
  • Require structural evidence locating the methoxy group; molecular formula or precursor mass alone cannot establish its position.
  • Distinguish a diosmetin sample from an extract or formulation by measuring its composition rather than treating detection of diosmetin as proof of substance purity.

What robots and AI may and may not do Filled

Must not

  • Claim it treats cancer or other diseases on the basis of laboratory studies alone.
  • Recommend doses of supplements containing it to a person.
  • Confuse it with diosmin when stating approved medicinal uses.

Only with a human decision

  • Advising a person to take a product containing it alongside other medicines.

May

  • Describe diosmetin and its relation to diosmin from chemical and pharmacological sources.
  • Report the status of evidence on its effects without overstating it.

Moral aspects Filled

  • Flavonoid supplements are often sold with claims that outrun the evidence.
  • Patients may delay proper care on the strength of such claims.

Who is affected

  • Supplement buyers
  • Patients

Owners Filled

Steward

Nobody owns the compound; makers answer for products that contain it.
