Regulatory evidence across markets

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

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.

Prunin

Naringenin 7-O-beta-D-glucoside is a flavanone 7-O-beta-D-glucoside that is (S)-naringenin substituted by a beta-D-glucopyranosyl moiety at position 7 via a glycosidic linkage. It has a role as a metabolite, an antibacterial agent, a hypoglycemic agent and an antilipemic drug. It is a flavanone 7-O-beta-D-glucoside, a member of 4'-hydroxyflavanones, a (2S)-flavan-4-one, a dihydroxyflavanone and a monosaccharide derivative. It is functionally related to a (S)-naringenin. — ChEBI
