Myricetin 3-O-galactoside(CAT: M133256) is a naturally occurring flavonol glycoside, consisting of the antioxidant flavonoid myricetin conjugated with a galactose sugar at the 3-O position. This glycosylation improves solubility, stability, and bioavailability while retaining the parent flavonoid’s strong antioxidant and anti-inflammatory activities. Found in fruits and medicinal plants, Myricetin 3-O-galactoside exhibits additional antimicrobial, cardioprotective, and potential anticancer properties. It serves as a valuable standard in phytochemical analysis, natural product chemistry, and pharmacognosy, as well as a promising candidate in drug discovery and nutraceutical development. Its dual structure provides opportunities to explore structure–activity relationships of glycosylated flavonoids.
