Direct factory supply of standardized plant extracts, pharmaceutical-grade monomers, and liposomal formulations with complete batch traceability.
From raw harvest validation to specialized column chromatography purification, we operate as a dedicated manufacturing partner rather than an intermediary broker.
Every shipment is delivered with comprehensive batch documentation, including HPLC/UV assay verification, heavy metal panels, pesticide residue reports (compliant with USP/EP standards), residual solvent analysis, and full microbiological clearance.
We deploy eco-friendly solvent-free Supercritical Fluid Extraction (SFE-CO2) alongside membrane concentration systems to yield oil-soluble and volatile plant active compounds without thermal degradation or toxic organic solvent residues.
Tailored physical specs: micronized ultra-fine powders (up to 500 mesh), direct compression (DC) granules, liposomal encapsulation, custom carrier formulations (maltodextrin, rice starch, gum arabic), and water-soluble complexes.
Our manufacturing plants in Xi'an, Shaanxi operate strict Quality Management Systems under cGMP guidelines. We strictly control every link in the chain—from raw material harvest at contracted planting bases to raw herb extraction, column purification, spray drying, and final clean-room packing.
The global botanical extracts and functional herbal powder market is undergoing a structural transformation. Buyers across the nutraceutical, pharmaceutical, cosmeceutical, and functional food sectors no longer view botanical powders simply as bulk raw materials. Instead, purchasing decisions are driven by information gain, verifiable purity monographs, bioavailability enhancements, and rigorous supply chain transparency.
As global regulatory bodies (including the US FDA, EFSA, and NMPA) tighten dietary supplement compliance and safety standards, procurement strategies among brand owners are changing significantly:
Achieving stable chemical assay percentages while preserving volatile herbal compounds requires multi-stage industrial engineering. Below is an overview of processing technologies utilized in modern OEM/ODM manufacturing:
| Technology Platform | Primary Processing Mechanism | Target Compounds | Industrial OEM Advantages |
|---|---|---|---|
| Supercritical CO2 Extraction (SFE) | High-pressure fluid CO2 solvent system without thermal degradation | Lipophilic actives, Essential oils, Gromwell Root, Oleoresins | 100% solvent-free, retains delicate lipophilic fractions, zero chemical residue |
| Column Chromatography Purification | Macroporous resin separation & recrystallization | High-purity Monomers (Quercetin 98%, Dihydromyricetin) | Delivers precise single-monomer purity compliant with EP/USP reference standards |
| Liposomal & Phytosome Encapsulation | Phospholipid membrane lipid bilayer entrapment | Flavonoids, Liposomal Quercetin 50%, Silybin Phospholipids | Dramatically increases intestinal absorption and cellular uptakes in finished dosage forms |
| Low-Temperature Spray Drying | Micro-atomization under vacuum thermal monitoring | Standardized Plant Powders, Sophora Japonica Extracts | Preserves phytochemical active structures, controls moisture content below 5.0% |
Quercetin (3,3',4',5,7-pentahydroxyflavone) is one of nature's most potent antioxidant and anti-inflammatory flavonoids. The industrial production of pure Quercetin relies predominantly on the flower buds of Sophora Japonica L. (Japanese Pagoda Tree), which contain exceptionally high concentrations of the precursor glycoside Rutin.
Our industrial extraction pathway follows a rigorous sequence:
Technical clarity for purchasing managers, quality control specialists, and brand formulators.
Every shipment is issued with a batch-specific Certificate of Analysis (COA) containing assay results (HPLC/UV), loss on drying, ash content, heavy metals (Lead, Arsenic, Cadmium, Mercury), microbiological counts (Total Plate Count, Yeast & Mold, E. coli, Salmonella), and pesticide panels compliant with EU/USP standards. Additional documentation including MSDS, Technical Data Sheets (TDS), Flowcharts, Allergen Declarations, and Non-GMO statements are available upon request.
For standard catalog inventory (such as Quercetin Powder 95%/98%), our standard MOQ is 1 kg for sample validation trials and 25 kg (standard fiber drum) for commercial supply. For custom OEM particle mesh processing, liposomal encapsulation, or tailored carrier ratios, pilot MOQ starts at 50 kg to 100 kg depending on product specs.
Standard Quercetin powder is poorly soluble in water and has limited gastrointestinal absorption. Liposomal Quercetin encapsulates the active flavonoid inside a sunflower or soy lecithin phospholipid sphere. This protects the active compound through gastric transit, allows direct cellular transport, and increases total systemic bioavailability up to 5-fold, enabling lower clinical dosages in premium dietary supplements.
We provide full-spectrum contract manufacturing services, including custom particle sizing (from 80 mesh to 500 mesh ultra-fine micronization), granulation for direct compression, custom excipient/carrier blending (Maltodextrin, Rice Flour, Gum Arabic), liposomal liquid/powder conversion, private labeling, and custom bulk drum packaging under nitrogen flush protection.
We source raw plant material exclusively from verified, long-term contracted planting bases. Raw herbs undergo strict testing upon factory intake. During production, multi-stage filtration and resin chromatography remove heavy metals and lipophilic pesticides. Final lots undergo analytical testing via GC-MS/MS and LC-MS/MS to ensure compliance with strict European Regulation (EC) No 396/2005 and USP limits.
Evaluation samples (10g–50g free sample vials) ship via air courier (DHL/FedEx) within 2 to 4 business days. Commercial orders of standard stock ship within 5 to 7 working days. Custom OEM/ODM batches requiring dedicated extraction or granulation runs typically ship within 15 to 20 business days following technical specification freeze.
