Standardized Quercetin Dihydrate Powder (95% - 98% HPLC)

What is Quercetin Dihydrate Powder?

Green Spring Technology’s premium Quercetin Dihydrate Powder is a highly purified, plant-derived flavonoid standardized from the premium botanical source Sophora japonica L. (Flower buds).

Engineered for commercial manufacturing, this bulk raw material is strictly standardized to contain 95% to 98% Quercetin Dihydrate by HPLC, guaranteeing maximum bioactivity, superior crystalline stability, and flawless batch-to-batch uniformity.

As a high-performance functional ingredient, this clean-label powder functions as a potent cellular antioxidant designed to enhance immune system response, support cardiovascular health, and promote anti-inflammatory pathways in advanced dietary supplements.

Specification

Quality & Compliance  

• Uncompromised Global Certifications
  Green Spring Technology ensures absolute regulatory compliance across global markets. Our manufacturing facilities and supply chains are fully audited and certified under BRC, IFS, ISO9001, and ISO22000 quality management systems, while our products hold verified FDA registration, COSMOS approval, Halal, Kosher, EU Organic, and USDA Organic certifications to facilitate seamless international customs clearance.

• Rigorous Impurity Elimination
  We minimize formulation risks through a proactive contamination control strategy. Every batch of our Quercetin Dihydrate Powder undergoes strict screening to guarantee that Heavy Metals (Pb, As, Cd, Hg), Pesticide Residues, and Solvent Residues remain well below the maximum residue limits (MRLs) defined by the European Pharmacopoeia (EP), United States Pharmacopeia (USP), and EC Regulations.

• Flawless Microbiological Security
  To safeguard consumer health and protect your brand reputation, we enforce a zero-tolerance policy for pathogenic contamination. Every shipment is backed by an independent Certificate of Analysis (CoA) confirming negative results for E. coli, Salmonella, and Staphylococcus aureus, ensuring total microbiological purity prior to dispatch.

Key Advantages for Formulators

• Superior Crystalline Stability
  Our manufacturing process preserves the optimal dihydrate crystalline structure of the molecule. This prevents any chemical degradation, discoloration, or active ingredient loss during aggressive high-speed capsule filling and tableting processes.

• Optimized Particle Distribution
  The powder is micronized and standardized to a uniform particle size, which drastically enhances its matrix dispersion in solid dosage forms. This consistent granulometry accelerates the natural dissolution rate in the digestive tract, successfully optimizing the bioactive ingredient’s bioavailability.

• 100% Clean Label & Non-GMO
  Sourced entirely from premium Sophora japonica flower buds, this pure botanical extract contains zero synthetic carriers, chemical anti-caking agents, or common allergens. It allows premium consumer brands to easily meet strict clean-label, plant-based, and non-GMO market requirements.

• Excellent Powder Flowability
  Engineered with an optimized bulk and tapped density, the powder flows smoothly through automated manufacturing hoppers. This complete processability prevents material caking, significantly reduces production downtime, and maximizes your batch-to-batch yield efficiency.

Applications

• Dietary Supplements
  Our bulk raw material is highly optimized for premium lifestyle and longevity supplements. It integrates seamlessly into hard gelatin capsules, vegetable capsules, and solid tablets, allowing brands to develop powerful formulas targeted at immune defense, cardiovascular wellness, and cellular longevity.

• Cosmetics & Personal Care
  Fully compliant with strict COSMOS standards, this high-purity powder serves as a premium active ingredient for clean-beauty formulations. It is ideal for anti-aging serums, topical creams, and protective skincare emulsions designed to support skin barrier resilience and reduce cellular oxidative stress.

• Functional Food & Beverages
  Engineered to meet clean-label market requirements, the powder can be utilized in dry-mix wellness formulations. It is perfectly suited for nutritional powder mixes, meal replacement shakes, and fortifying nutritional bars without compromising the structural integrity of the food matrix.

• Nutraceutical Confectionery
  Our optimized granulometry ensures a highly uniform powder distribution in confectionery delivery systems. It is an excellent functional additive for active nutritional gummies, chewable tablets, and fortified lozenges, which are currently experiencing rapid consumer demand growth worldwide.
