Myricetin 3-O-galactoside has cytotoxicity, antioxidant, anti-genotoxic, antinociceptive and anti-inflammatory effects, the effects are related to peripheral inhibition of nitric oxide synthesis, mainly inducible nitric oxide synthase (iNOS).

Antimutagenic activity was assessed using the SOS chromotest and the Comet assay. The IC50 values of lipid peroxidation by Myricetin 3-O-galactoside and myricetin 3-o-rhamnoside are respectively 160 microg/ml and 220 microg/ml. At a concentration of 100 microg/ml, the two compounds showed the most potent inhibitory effect of xanthine oxidase activity by respectively, 57% and 59%. Myricetin 3-o-rhamnoside was a very potent radical scavenger with an IC50 value of 1.4 microg/ml. Moreover, these two compounds induced an inhibitory activity against nifuroxazide, aflatoxine B1 and H2O2 induced mutagenicity.
