Pioneering extraction processes, high active ingredient thresholds, and customizable purity standards built for global pharmaceutical and nutraceutical distribution.
Rutin, chemically known as quercetin-3-O-rutinoside, is a prominent low-molecular-weight glycoside composed of the flavonol quercetin and the disaccharide rutinose. Universally classified within the "Vitamin P" family, it represents one of the most therapeutically versatile plant secondary metabolites. Sophora japonica (the Chinese Pagoda Tree) serves as the primary botanical reservoir for commercial extraction, yielding industrial-scale raw materials crucial for pharmaceutical formulations, cardiovascular nutraceuticals, and high-performance dermatological topicals.
For decades, Rutin has occupied a leading position in vascular medicine. It acts directly on the microvascular endothelium, strengthening capillary walls, correcting abnormal permeability, and alleviating venous insufficiency. As a powerful scavenger of reactive oxygen species (ROS), Rutin protects cellular membranes against lipid peroxidation, offering profound structural benefits in preventing chronic inflammatory diseases and vascular aging.
As a leading Rutin Vitamin P exporter, we maintain rigorous chemical specifications compliant with global pharmacopoeias:
| Analytical Parameters | Standard Specification |
|---|---|
| Assay (HPLC/UV-Vis) | 95.0% - 98.5% (Anhydrous Basis) |
| Heavy Metals | ≤ 10 ppm |
| Pesticide Residue | Complies with USP <561> |
| Loss on Drying | 5.0% - 8.5% |
| Residual Solvents | Ethanol Only (Methanol Free) |
An analytical breakdown of the international bioflavonoid market, macro supply chains, and evolving regulatory boundaries.
China accounts for over 70% of the world's commercial Sophora japonica cultivation and extraction, placing Chinese exporters at the absolute center of the global Rutin supply pipeline. Raw materials are harvested from high-yield, altitude-optimized regions and processed using modern ethanol extraction and crystallization loops, serving key markets across the EU, North America, and emerging bio-hubs in Latin America and the APAC region.
Driven by the global transition toward preventive healthcare, chronic venous disease therapies, and plant-derived antioxidants, the international Rutin market is projected to expand at a steady CAGR. Buyers are demanding increasingly stringent purity standards, pushing manufacturers to phase out obsolete chemical solvents in favor of clean-label water/ethanol extraction setups.
In mature economies, Rutin and its active derivatives must navigate complex regulatory environments. The US FDA regulates it under DSHEA guidelines, demanding self-affirmed GRAS or strict dietary supplement safety validation. In the EU, compliance requires conforming to European Pharmacopoeia (EP) criteria and navigating European Food Safety Authority (EFSA) opinions on botanical health claims.
Established in 2012, Chengdu Chenlv Herb Co., Ltd. has developed into a prominent, high-tech enterprise specializing in the R&D, processing, customization, and export of premium plant extracts and natural pharmaceutical ingredients.
Operating from a modern 9,514 square meter facility, we harness the wealth of natural resources in Southwest China.

How our advanced Rutin Vitamin P processing pipeline addresses complex formulation issues in multi-sector product development.
Microvascular weakness leads to systemic edema, varicose veins, and diabetic retinopathy. Rutin inhibits hyaluronidase and lysosomal enzymes that degrade the extracellular matrix, restoring capillary resistance. Our high-crystallinity Rutin is optimized for integration with horse chestnut extract and vitamin C, creating powerful synergistic formulas for venous health.
Rutin's naturally low aqueous solubility limits its bioavailability in oral formulations. We address this using physical micronization and co-crystallization methodologies. By optimizing particle size distribution, we improve the compound's dissolution rate and absorption kinetics, supporting clean-label supplement formulations without synthetic additives.
Modern functional foods and nutraceuticals rely on multi-ingredient synergies. We supply key complementary extracts—including Quercetin, Hesperidin Methyl Chalcone, and Siberian Ginseng—allowing clients to source compatible active ingredients from a single, audited manufacturer.

Key technical, chemical, and logistical questions answered by our laboratory and quality assurance teams.
Although Rutin is present in buckwheat, eucalyptus leaves, and citrus fruits, commercial-scale extraction relies almost entirely on the dried flower buds of Sophora japonica L. (the Chinese Pagoda Tree). Sophora japonica provides the highest natural concentration of the active compound, yielding stable extracts with high purity and batch-to-batch consistency.
Rutin is a glycoside composed of the aglycone quercetin bound to the disaccharide rutinose. This sugar moiety makes Rutin highly stable but reduces its absorption speed in the upper digestive tract. Intestinal enzymes must first cleave the sugar bond to release the free quercetin, which is then absorbed. Our R&D team uses advanced physical milling techniques to optimize absorption kinetics.
Our quality control process starts at the cultivation level. We test every incoming batch of raw Sophora japonica for heavy metals (using Inductively Coupled Plasma Mass Spectrometry) and pesticide residues (via Gas Chromatography-Mass Spectrometry), ensuring complete compliance with USP <561> and European Pharmacopoeia limits before processing.
Through our structured 7-step customization workflow, we tailor particle sizes, density profiles, and assay purities to meet specific client needs. We also formulate custom blend matrices—combining Rutin with complementary bioflavonoids like Hesperidin or Quercetin—to support targeted therapeutic applications.
As a natural polyphenol, Rutin is sensitive to direct sunlight, high heat, and humidity. We recommend storing the material in its original double-bagged packaging in a cool, dry warehouse environment. Under these conditions, the compound maintains its purity and active assay profile for a minimum of 24 months.
Providing a comprehensive portfolio of standardized plant extracts to support modern clinical formulations and functional food designs worldwide.
