Dihydroquercetin extracted from high-quality dry Engelhardia roxburghiana leaves. As a national high-tech enterprise, we integrate natural sourcing, advanced extraction technology and strict quality control to deliver a premium natural active ingredient to global partners.
Our Dihydroquercetin has excellent specifications: white to off-white fine powder (CAS 480-18-2, C₁₅H₁₂O₇), with adjustable purity (90%, 95%, 98% by HPLC), and good solubility.
We exclusively use high-quality dry Engelhardia roxburghiana leaves, a precious medicinal plant naturally rich in Dihydroquercetin. Each product batch undergoes 546-item pesticide residue testing and strict quality checks, meeting EU and US standards for safety and purity.
We adopt the optimized acid hydrolysis extraction method: crushing dry leaves into 40-60 mesh powder, soaking in ethanol for extraction, hydrolyzing with hydrochloric acid to release free Dihydroquercetin, then extracting with ethyl acetate, concentrating and freeze-drying. This method ensures a 92% extraction rate, no harmful reagents, and eco-friendly production.
The product has remarkable efficacy: as a natural bioflavonoid, it offers strong antioxidant, anti-inflammatory and neuroprotective effects, scavenging free radicals and protecting cell integrity. It is 3.4-4.9 times more effective in protecting capillary function than ordinary quercetin, with FDA GRAS certification for high safety.
Its applications are extensive: pharmaceuticals (cardiovascular and neuroprotective drugs), food supplements (anti-aging and immune-boosting products), and cosmetics (anti-aging, moisturizing formulations). Certified by FDA, FSSC22000, KOSHER and HALAL, it enables easy global market access.
Nuoz Biotech is committed to high-quality natural extracts. We welcome global partners to cooperate, explore its application prospects and build a healthier future. Contact us for more details!
