Myricetin 3-O-galactoside (Myricetin 3-O-beta-D-galactopyranoside) can inhibit xanthine oxidase (xanthine oxidase; XO) activity, lipid peroxidation and scavenging free radicals. Myricetin 3-O-galactoside has many effects, including cytotoxicity, anti-oxidation, anti-genotoxicity, anti-infectivity, anti-inflammatory and antioxidant activities, and its main effect is to inhibit the synthesis of inducible nitric oxide synthase (iNOS). The IC50 of Myricetin 3-O-galactoside inhibited lipid peroxidation was 160 μg/mL.

| In vitro | The anti-mutagenesis activity was evaluated by SOS color rendering test and Comet test. The IC50 values of myricetin 3-O-galactoside and myricetin 3-o-rhamnoside for lipid peroxidation were 160 μg /ml and 220 μg /ml, respectively. At the concentration of 100 μg /ml, the two compounds showed the strongest inhibitory effects on xanthine oxidase activity (57% and 59%, respectively). Myricetin 3-0-rhamnoside is a very effective free radical scavenger with an IC50 value of 1.4 MCG/ml. In addition, these two compounds showed inhibitory activity against mutagenesis induced by nifuran, aflatoxins B1 and H2O2[1]. |
