Description

Quercetin 3-o-Malonylglucoside is a specific, naturally occurring flavonoid glycoside derived from plants. This compound is valued for its role as a key biochemical marker and active ingredient in research and product development. It is primarily sought by professionals in the nutraceutical, pharmaceutical, and cosmetic industries for applications in antioxidant studies, natural product standardization, and the formulation of bioactive products.

Application

• As a reference standard for the quality control and authentication of botanical extracts, particularly those containing quercetin derivatives.
• As a key biochemical marker in plant physiology and metabolomics research to study flavonoid biosynthesis and plant stress responses.
• As a potential active pharmaceutical ingredient (API) intermediate for the development of nutraceuticals and dietary supplements focused on antioxidant support.
• In cosmeceutical formulations for its antioxidant properties, aimed at protecting skin from environmental oxidative stress.
• For in-vitro research into the bioavailability, metabolism, and biological activities of flavonoid compounds.
• In the development of functional foods and beverages where standardized flavonoid content is required for efficacy claims.
