Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name KAEMPFEROL RHAMNOSIDE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Afzelin

Afzelin is a glycosyloxyflavone that is kaempferol attached to an alpha-L-rhamnosyl residue at position 3 via a glycosidic linkage. It has a role as an antibacterial agent, an anti-inflammatory agent and a plant metabolite. It is a trihydroxyflavone, a glycosyloxyflavone and a monosaccharide derivative. It is functionally related to a kaempferol. It is a conjugate acid of an afzelin(1-). — ChEBI
