High-Purity Sophora Japonica Extract (Rutin & Quercetin) Manufacturing
Sophora Japonica (Huai Mi) is recognized worldwide as the supreme botanical matrix for the industrial extraction of bioflavonoids. Operating at the core of Shaanxi's raw material belt, our facility executes large-scale, green continuous extraction, transforming botanical raw buds into ultra-purified NF, USP, and EP-grade Quercetin and Rutin bulk powders.
Bioflavonoid Bioavailability
Our enzymatic hydrolysis protocols convert native Rutin glycosides into aglycone Quercetin with crystalline structural precision, achieving rapid systemic dissolution and enhanced bioavailability in oral solid dosage forms.
Supercritical & Low-Temp Clean Prep
Employing closed-loop water-ethanol countercurrent extractions and low-temperature vacuum crystallization prevents thermal degradation of active polyphenols and maintains polycyclic integrity without toxic solvents.
Monograph Release Conformity
Every industrial batch aligns with EP (European Pharmacopoeia) and USP monographs, audited using calibrated Agilent HPLC, ICP-MS for heavy metals, and validated microbiological assays.
Macro Industry Challenges & Sourcing Solutions
Navigating complex international raw-material markets requires supply elasticity, documented impurity controls, and multi-jurisdictional compliance.
Traceability & GAP Agriculture
Global procurement teams struggle with seasonal pricing fluctuations and unvetted pesticide residues. ShineHerb circumvents this via long-term contracts with Shaanxi GAP-compliant agricultural bases, ensuring unadulterated starting material with fully documented harvest provenance.
Strict Regulatory Clearance
Import holds at EU and US ports typically result from PAH, pesticide, or mycotoxin non-conformity. Our fully integrated labs perform LC-MS/MS pesticide screens (covering over 400 parameters under EC 396/2005) before release to guarantee effortless customs clearance.
Formulation Flexibility & Particle Engineering
Modern dosage formats—such as sparkling RTD beverages, high-density direct compression tablets, and liposomal suspensions—demand tailored physical characteristics. We engineer mesh sizes (80 mesh to 200 mesh micronization) and custom bulk densities for seamless factory blending.

Advanced Manufacturing Pipeline & Future Outlook
Transforming conventional botanical isolation into digitalized continuous extraction systems.
Continuous Countercurrent Line
High-efficiency multi-stage countercurrent extraction cascades achieve complete recovery of botanical flavonoids while reducing thermal residence time to under 40 minutes, safeguarding labile molecular structures.
Liposomal Micro-Encapsulation
To resolve the intrinsic lipophilicity and poor aqueous solubility of Quercetin, our R&D engineering hub deploys patented lipid bilayer encapsulation technologies, boosting cellular transport up to 20-fold.
Synthetic Biology Synergies
Our 2026-2030 roadmap pioneers precision bio-fermentation fermentation routes yielding highly pure aglycones, drastically slashing our carbon footprint and assuring an endless bio-identical ingredient supply.
Standardized Verification for Borderless Distribution
We assist regulatory affairs departments by furnishing end-to-end qualification dossiers, valid certifications, and full third-party test data.
24/7 Regulatory Concierge
Direct communication with qualified chemists who supply raw material DMF technical packages, stability profiles (accelerated and long-term testing under ICH guidelines), TSE/BSE statements, and allergen certifications.
Consolidated Supply Chain Hubs
Export packaging complies with strict transport handling requirements: 25kg double-polythene lined pharmaceutical fiber drums with moisture-resistant foil barriers, palletized with heat-treated ISPM-15 certified wood for flawless air and sea shipping.
Frequently Asked Questions by Industrial Sourcing Teams
Immediate scientific clarity on extraction yields, testing protocols, documentation, and contract deliveries.
What is the standard purity difference between Quercetin Dihydrate and Anhydrous?
Quercetin Dihydrate contains two bound water molecules (approx. 9.5-12.0% water content by Karl Fischer titration), typically yielding an assay of 95.0% to 98.0% on an anhydrous basis. Quercetin Anhydrous undergoes controlled thermal vacuum dehydration, resulting in <3.0% loss on drying and an assay typically exceeding 98.0% HPLC, making it ideal for moisture-sensitive formulations.
How does ShineHerb ensure residual solvent control in Sophora Japonica extracts?
Our extraction lines utilize strictly purified water and food-grade ethanol as primary extraction menstruums. Volatile impurities are completely removed in falling-film vacuum evaporators. Residual ethanol levels are documented well below USP <467> and EP Option 1 guidelines (<5000 ppm, typically <500 ppm in routine batches) via Headspace Gas Chromatography (GC-FID).
What documents accompany our wholesale shipments?
Every commercial batch is accompanied by an authentic, lot-specific Certificate of Analysis (COA) containing HPLC chromatograms, full heavy metal counts (Pb, As, Cd, Hg), microbial status (total viable count, yeast/mold, absence of E. coli & Salmonella), Safety Data Sheet (SDS/MSDS), and non-GMO/Allergen declarations.
Can you provide custom particle sizing or wet granulation for direct tablet compression?
Yes. Sophora Japonica powder naturally possesses needle-shaped crystals with low bulk density and poor flowability. We provide custom air-jet micronization (down to D90 < 20μm) for suspensions and fluid-bed granulation with standard binders (PVP or HPMC) to generate high-density granules tailored for high-speed rotary tablet presses.
