Regulatory evidence across markets

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

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.

Myricitrin

Myricitrin is a glycosyloxyflavone that consists of myricetin attached to a alpha-L-rhamnopyranosyl residue at position 3 via a glycosidic linkage. Isolated from Myrica cerifera, it exhibits anti-allergic activity. It has a role as an EC 2.7.11.13 (protein kinase C) inhibitor, an anti-allergic agent, an EC 1.14.13.39 (nitric oxide synthase) inhibitor and a plant metabolite. It is a pentahydroxyflavone, an alpha-L-rhamnoside, a glycosyloxyflavone and a monosaccharide derivative. It is functionally related to a myricetin. It is a conjugate acid of a myricitrin(1-). — ChEBI
