Description

Taxifolin 3-o-Rhamnoside is a specific flavonoid glycoside derived from the natural compound taxifolin (dihydroquercetin). This compound matters for its enhanced bioavailability and targeted bioactivity compared to its aglycone form, making it a valuable intermediate for advanced research and product development. It is primarily needed by manufacturers and researchers in the nutraceutical, pharmaceutical, and cosmetic industries seeking to leverage its antioxidant and potential therapeutic properties.

Application

• Nutraceutical Ingredient: Used as a key active component in dietary supplements targeting oxidative stress and inflammation.
• Pharmaceutical Research: Serves as a reference standard and a potential intermediate for developing novel therapeutic agents.
• Cosmetic Formulations: Incorporated into anti-aging and skin-protective products for its antioxidant capabilities.
• Functional Food & Beverages: Added to enhance the health-promoting profile of fortified food and drink products.
• Biochemical Research: Utilized in studies investigating flavonoid metabolism, glycosylation effects, and structure-activity relationships.
• Standard for Quality Control: Employed as an analytical standard to ensure the purity and authenticity of taxifolin-based raw materials and finished products.

Quality Control

Our Taxifolin 3-o-Rhamnoside is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) documenting purity, residual solvents, and heavy metals are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
