Description

Eriodictyol 7-o-β-D-Glucuronide Ethyl Ester is a high-purity, semi-synthetic flavonoid derivative, specifically a glucuronide conjugate of the natural flavanone eriodictyol. This compound is valued for its enhanced bioavailability and metabolic stability compared to its aglycone precursor, making it a critical reference standard and a promising candidate for advanced research. It is primarily sought by pharmaceutical R&D, nutraceutical, and cosmeceutical industries for developing novel therapeutic and bioactive formulations.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of eriodictyol metabolites in pharmacokinetic and bioequivalence studies.
• Bioavailability & Metabolism Research: Serves as a key intermediate or metabolite model to study the absorption, distribution, and glucuronidation pathways of flavonoid compounds.
• Nutraceutical Ingredient Development: Investigated for incorporation into advanced dietary supplements targeting antioxidant, anti-inflammatory, and neuroprotective health benefits.
• Cosmeceutical Actives: Evaluated in skincare formulations for its potential anti-aging and protective effects against environmental oxidative stress.
• Biochemical Research: Utilized as a substrate or inhibitor in enzymatic assays related to glucuronosyltransferases (UGTs) and other metabolic enzymes.
• Analytical Method Development: Acts as a critical calibration standard for developing and validating HPLC, LC-MS, and other chromatographic methods for flavonoid analysis.
