Description

Reynoutrin is a high-purity flavonoid compound, also known as quercetin-3-O-rhamnoside, widely recognized for its potent biological activity. This compound is essential for research and development in the pharmaceutical and nutraceutical sectors due to its antioxidant and anti-inflammatory properties. It serves as a critical standard and active ingredient for manufacturers in dietary supplements, functional foods, and advanced cosmetic formulations.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for quality control and analytical method development in drug manufacturing.
• Nutraceutical Formulations: Incorporated into dietary supplements and functional food products for its antioxidant and health-promoting benefits.
• Cosmetic Actives: Serves as a key bioactive ingredient in anti-aging, skin-brightening, and protective skincare serums and creams.
• Biochemical Research: Utilized in in vitro and in vivo studies to investigate mechanisms of action related to inflammation, oxidative stress, and metabolic pathways.
• Natural Product Extraction & Standardization: Acts as a marker compound for the standardization of plant extracts derived from sources like Reynoutria japonica (Japanese Knotweed) and Sophora japonica.
