Description

Kaempferol 3-o-α-Rhamnopyranosyl(1-2)-β-Galactopyranoside-7-o-β-Glucopyranoside is a highly purified, complex flavonoid glycoside derived from natural sources, offering a standardized bioactive compound for research and development. This specific glycosylated derivative of kaempferol is valued for its enhanced solubility and bioavailability compared to its aglycone form, making it a critical reference standard and active ingredient. It is primarily sought by the pharmaceutical, nutraceutical, and cosmeceutical industries for advanced studies in inflammation, oxidative stress, and metabolic health.

Application

• Pharmaceutical Reference Standard: Used as a high-purity certified reference material (CRM) for analytical method development, validation, and quality control in drug discovery and herbal medicine.
• Nutraceutical Formulation: Incorporated into dietary supplements and functional foods for its potential antioxidant and anti-inflammatory properties.
• Cosmetic Actives: Serves as a key bioactive ingredient in anti-aging and skin-protective formulations due to its potential to combat oxidative damage.
• Biochemical Research: Essential tool for in vitro and in vivo studies investigating flavonoid metabolism, bioavailability, and molecular mechanisms of action.
• Natural Product Isolation & Standardization: Used to standardize extracts from plants like Sophora japonica (pagoda tree) and other botanical sources rich in flavonoid glycosides.
