Definition
US FDA substance register · UNII 5Z0ZO61WPJ · registered name MYRICITRIN · single chemical substance
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-).
