Regulatory evidence across markets

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

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.

Piceatannol

Piceatannol is a stilbenol that is trans-stilbene in which one of the phenyl groups is substituted by hydroxy groups at positions 3 and 4, while the other phenyl group is substituted by hydroxy groups at positions 3 and 5. It has a role as a geroprotector, a hypoglycemic agent, an antineoplastic agent, a protein kinase inhibitor, a tyrosine kinase inhibitor, an apoptosis inducer and a plant metabolite. It is a polyphenol, a member of catechols, a member of resorcinols and a stilbenol. It derives from a hydride of a trans-stilbene. — ChEBI
