Active Components and Bioactivity
The primary active component of our extract is Stilbene Glycoside (TSG), which can range from 2% to 50% depending on your demands. By boosting the synthesis of tyrosinase and MITF, this compound promotes the synthesis of melanin in hair follicles.
Our controlled extraction method reduces the concentrations of free anthraquinones (such emodin and physcion) to safe levels in order to address liver toxicity concerns and maintain the product's effectiveness.
Polysaccharides, phospholipids, and significant trace metals including zinc and iron are also included in the extract. Each batch is verified using fingerprint chromatography, which ensures that the product stays constant during production and stops the admission of counterfeit components.
Quality Control and Safety Standards
We use thorough testing procedures that are in line with EU Pharmacopeia and USP standards. Heavy metal testing measures levels of lead, arsenic, mercury, and cadmium using cutting-edge ICP-MS technology.
Microbial testing checks for Salmonella, E. Coli, yeast and mold, and Total Plate Count to ensure client safety. Pesticide residue levels are confirmed to meet international criteria by our GC-MS/MS analysis.
TSG measurement using HPLC guaranties that your formulations will have the physiological activity they require. The levels of emodin and physcion are tightly regulated to avoid any negative effects while preserving the extract's conventional advantages.

Industrial Applications
Cosmeceutical Formulations: Anti-aging skincare and hair care products include our Polygonum Multiflorum Extract as a premium component. In scalp serums and shampoos, it helps prevent early graying and hair loss by assisting the body in repairing natural pigments.
Nutraceutical Manufacturing: TSG is utilized in supplements that promote a longer life because it is a potent antioxidant. It shields the brain and heart from harm brought on by free radicals in items for senior citizens.
Functional Beverages: Because the extract remains stable when heated, it works well in powdered drinks and health tonics. Because it continues to work even after pasteurization and over time, it is also utilized in products for kidney and liver health.
