Myricitrin is a naturally occurring polyphenol hydroxy flavonoid. Myricitrin has a variety of beneficial properties, such as antiviral, antimicrobial, antinociceptive, and anticarcinogenic activities. In particular, myricitrin possesses stronger oxidative resistance and free radical scavenging activity than other flavonol rhamnosides or quercetin. Myricitrin showed antipsychotic-like effects in animal models at doses that did not induce catalepsy or alter locomotor activity, suggesting that myricitrin may be a potential drug treatment for the positive symptoms of schizophrenia.

In Vivo Use Guide

Mice: 5, 10, and 30 mg/kg

Route of Administration: Intraperitoneal

In Vitro Use Guide

RAW264.7 cells were pretreated with 400 ug/ml myricitrin for 2 h or not and then were incubated with LPS (100 ng/ml) for 15 min. Noncytotoxic level of myricitrin inhibited p47phox which was transferred to the membrane and suppressed the interaction between p47phox and gp91phox.
