Dihydroquercetin, also known as taxifolin, is a flavonoid extracted from the heartwood of the Siberian Larch tree. This listing confirms the product is sourced exclusively from this botanical origin, with a purity level of at least 95% as stated in the supplier's data. The compound is presented as a fine, pale yellow to off-white powder, soluble in ethanol and water, with a typical melting point between 305°C and 310°C.
The extraction process retains the natural stereochemistry of the molecule, preserving its antioxidant capacity. In the nutraceutical industry, this form is commonly used for its free radical scavenging activity, with a standard ORAC value ranging from 30,000 to 40,000 µmol TE/g. Unlike synthetic analogs, this extract contains no solvents or stabilizers, and residual solvents are kept below 500 ppm as per ICH Q3C guidelines. The product is not irradiated or chemically modified.
Buyers include manufacturers of dietary supplements targeting cardiovascular and metabolic health, as well as cosmetic formulators seeking natural anti-aging agents. The product is typically packaged in 1kg aluminum foil bags with inner polyethylene liners, and bulk orders are available in 25kg drums. Trade terms are negotiable but commonly include FOB Shanghai or CIF destination port. Lead time is typically 10 to 15 days after payment confirmation, pending final order size.

Sourcing Dihydroquercetin from Wuxi Cima Science Co., Ltd. - China Import Guide
Before placing an order, verify the purity specification through a third-party lab test on a sample batch. Request a Certificate of Analysis showing HPLC chromatograms, heavy metal results, and microbial counts. Do not rely on supplier claims alone. Confirm the extraction source is Siberian Larch and not a cheaper substitute like pine bark. Request a sample with a documented batch number for lab testing prior to bulk purchase.
Confirm Incoterms, lead time, and packaging before shipment. FOB Shanghai is common, but ensure the supplier handles export documentation. Lead time is typically 10 to 15 days, but may extend during Chinese holidays. Packaging should be food-grade, moisture-resistant, and sealed with desiccant. Payment terms are usually T/T in advance or LC at sight. Always require a bill of lading and commercial invoice with full product description.
Perform incoming quality checks on every shipment. Test for purity via HPLC, moisture content by Karl Fischer, and microbial load using standard plate counts. Check for foreign matter and color consistency. Retain a sample from each batch for future reference. Ensure the supplier provides a full Certificate of Analysis signed by their quality manager. Document all test results and retain them for regulatory compliance, especially if the product enters the EU or US market.
