Application

Myricetin has been used:
  • to study its preventive effect as an antioxidant on noise-induced hearing loss (NIHL) in rats
  • as a flavonoid compound to test antiviral activity of Bourbon virus (BRBV) and in inhibition of RNA-dependent RNA polymerase (RdRP)
  • to study its effect as a treatment on biofilms of Streptococcus mutans and Candida albicans
  • as a reference standard for the quantification of phenolic compounds from Juniperus species

Biochem/physiol Actions

Myricetin exerts anti-oxidant effects, and anti-inflammatory effects by regulating multiple signal pathways. It also displays anti-diabetic and hepatoprotective effects. Myricetin strongly inhibits yeast α-glucosidase, glyoxalase I in vitro, and bovine milk xanthine oxidase. It also promotes complex formation between DNA and both topoisomerase I and II, an effect that may have implications in cancer chemotherapy. Myricetin also has various nutraceuticals values and therapeutic effects.

General description

Myricetin (MYR) is a natural polyhydroxyflavonol compound, first isolated from the bark of Morella rubra (Myrica rubra) tree.
