Myricitrin is a plant compound, the 3-O-α-L-rhamnopyranoside of myricetin.[1]


It can be isolated from the root bark of Myrica cerifera (Bayberry, a small tree native to North America), in Myrica esculenta, in Nymphaea lotus[2] and N. odorata, in Chrysobalanus icaco[3] and in Polygonum aviculare.[4]

Myricitrin is used by several beetle species in their communication system.[5] These include Plagioderma versicolora, Agelastica coerulea, Atrachya menetrisi, Altica nipponica, Altica oleracea, Gastrolina depressa.

Health effect[edit]

Myricitrin is a nitric oxide and protein kinase C inhibitor and exhibits antipsychotic-like and anxiolytic-like effects in animal models of psychosis and anxiety respectively.[6]
