Discover premium natural botanical extracts from Chengdu Chenlv Herb, optimized for pharmacological and nutraceutical efficacy.
In the evolving landscape of global health and clinical wellness, polyphenolic compounds—specifically flavonoids—have shifted from traditional therapeutic ingredients to cornerstone raw materials in modern functional biology. Among these, Quercetin and its glycoside form, Rutin (quercetin-3-rutinoside), represent a high-value category that undergoes intensive extraction and chemical characterization in specialized global facilities.
As a leading Quercetin Rutin factory, Chengdu Chenlv Herb Co., Ltd. addresses the growing global demand by supplying discount bulk ingredients that adhere to the highest pharmacopoeial standards. These compounds are commonly co-formulated due to their synergistic mechanism of action. While Quercetin operates as a highly potent scavenger of free radicals and an inhibitor of lipid peroxidation, Rutin enhances capillaries, improves microcirculation, and exhibits superior thermal and chemical stability under varied industrial processing states.
The global trade index for flavonoid-based active ingredients shows an upward trajectory. According to industrial intelligence reports, the compounded annual growth rate (CAGR) for Quercetin and Rutin compounds is projected at 7.2% through 2030. This expansion is driven by several key factors:
Operating as a raw material factory, Chenlv Herb ensures that global B2B procurement professionals secure reliable supply lines. Through vertical integration of botanical cultivation—primarily targeting Sophora japonica L. (Japanese pagoda tree)—the factory provides competitive cost mitigation, bypassing intermediaries and offering direct discount pricing structures on highly refined batches.

The industrial extraction of Quercetin and Rutin at Chengdu Chenlv Herb's 2,711㎡ facility is built upon high-precision, green engineering methodologies. The quality pipeline starts with harvesting prime Sophora japonica flower buds at specific developmental stages to maximize initial rutin concentration.
Our extraction roadmap utilizes a multi-stage process designed to preserve molecular activity while eliminating impurities:
Buds are extracted using food-grade ethanol and purified water. Automated PLC systems regulate temperatures below 60°C to prevent thermal degradation of the glycoside bonds.
Rutin is separated via temperature-controlled crystallization. To manufacture pure Quercetin, the rutin intermediate undergoes controlled acid hydrolysis to cleave the rutinoside disaccharide moiety, yielding highly pure Quercetin dihydrate.
For high-end pharmaceutical or cosmetic applications, macroporous resin column chromatography is employed to achieve purities exceeding 98% (HPLC assay).
As an international supplier, our product specifications align with the regulatory frameworks of major target markets:

The primary therapeutic limitation of crystalline Quercetin has historically been its low aqueous solubility and subsequent low absorption rates in the intestinal tract. To address this, Chenlv Herb’s R&D division is developing a series of next-generation delivery platforms:
1. Phytosomal Formulations: By complexing Quercetin with sunflower-derived lecithin, we form lipophilic phytosomes. Studies indicate this structure can increase intestinal epithelial absorption by up to 20-fold compared to unformulated active ingredients.
2. Co-Crystallization with Excipients: Using precise crystallization solvents, we co-crystallize Quercetin with biocompatible carriers like proline or nicotinamide, modifying the crystal lattice to increase water solubility without altering the chemical structure of the active molecule.
3. Enzymatically Modified Isoquercitrin (EMIQ): Converting rutin into soluble isoquercitrin via enzymatical glycosidation, yielding a derivative with exceptionally high bioavailability profiles suitable for carbonated RTD beverages and liquid supplements.
For B2B buyers, purchasing directly from a Chinese extraction factory offers structural advantages. Raw material yields for Sophora japonica are heavily dependent on domestic climate patterns. By maintaining substantial storage facilities in Chengdu, Chenlv Herb hedges against crop yield volatility, ensuring continuous supply lines and price stability for our contract partners.
Addressing technical, chemical, and supply chain questions for B2B buyers.
Quercetin (the aglycone) is a highly reactive antioxidant with lower water solubility, preferred for softgels, solid dose tablets, and cellular aging formulations. Rutin (the glycoside containing rutinose) exhibits superior stability under heat and light, possesses higher water solubility, and is favored for vascular health formulations, cosmetics, and beverage applications.
We enforce a strict non-irradiation, non-EtO sterilization policy. All batches undergo gas chromatography-mass spectrometry (GC-MS) testing to confirm PAH levels are well within European Commission Regulation limits, and no ethylene oxide residue is present. Detailed analytical reports are provided with every batch.
We use water and food-grade ethanol as extraction solvents. The residual solvent levels in the final dry powder are consistently below the USP <467> and EP guidelines for Class 3 solvents, ensuring a safe and clean chemical profile.
Yes, we offer custom milling and micronization. While our standard powder is 80 mesh, we can supply 120 mesh, 200 mesh, or custom granulated forms to optimize flowability, reduce dust, and prevent separation in dry-blend formulations.
We utilize direct sourcing contracts with local growers and maintain a strategic raw material reserve. This inventory buffer helps insulate our long-term supply partners from seasonal price spikes and agricultural market fluctuations.
