Regulatory evidence across markets

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

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.

Pectolinarin

Pectolinarin is a disaccharide derivative that consists of pectolinarigenin substituted by a 6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-glucopyranosyl moiety at position 7 via a glycosidic linkage. It has a role as an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor, an antioxidant, an antineoplastic agent, an anti-inflammatory agent, an apoptosis inducer and a plant metabolite. It is a dimethoxyflavone, a rutinoside, a monohydroxyflavanone, a glycosyloxyflavone and a disaccharide derivative. It is functionally related to a pectolinarigenin. — ChEBI
