High-purity bioactive molecules manufactured in compliance with international pharmaceutical standards.
Quercetin, a highly potent natural polyphenol flavonoid found abundantly in Sophora japonica, has become a pivotal focus of oncology research and integrative cancer therapy globally. As an OEM exporter, we supply high-purity Quercetin to global researchers, pharmaceutical manufacturers, and clinical nutrition brands investigating the biochemical pathways of cellular growth and mutation.
Scientific studies indicate that Quercetin exhibits selective cytotoxicity toward malignant cells while preserving normal tissue vitality. It acts dynamically on multiple cellular signaling cascades—specifically targeting the PI3K/Akt/mTOR pathway, inducing apoptosis via mitochondrial depolarization, and downregulating pro-inflammatory markers like NF-κB and IL-6. Our industrial-scale extraction processes ensure that clinical-grade Quercetin is optimized for bioavailability and systemic efficacy.
Furthermore, Quercetin serves as a powerful antioxidant and chemosensitizer. When utilized in adjuvant therapy research, it has demonstrated the potential to mitigate multidrug resistance (MDR) in cancer cell lines, enhancing the therapeutic efficacy of standard chemotherapeutic agents while shielding critical organs from treatment-induced oxidative strain. We provide customized OEM formulations specifically designed to overcome traditional absorption limitations through advanced particle sizing and carrier integration.
The global demand for botanical active ingredients, particularly high-purity flavonoids, has experienced exponential growth. Driven by the consumer pivot toward clean-label therapeutics and preventative health, the market for Quercetin raw materials has transitioned from localized herbal remedies to highly regulated, globally integrated supply chains.
As a leading Chinese supplier, Chengdu Chenlv Herb Co., Ltd. sits at the center of this global pipeline. Harvesting premium botanical inputs from high-altitude agricultural zones, we process and refine raw materials using state-of-the-art closed-loop solvent extraction facilities. This allows us to supply consistent volumes to primary markets across North America, the European Union, and Asia-Pacific, maintaining stability in both pricing and structural purity despite volatile global agricultural yields.
Strict import regulations in target markets have elevated the import threshold. Exporters must provide comprehensive scientific validation, including third-party testing for heavy metals, residual pesticides, and residual solvents (in accordance with USP <467> guidelines). We meet these demands by maintaining complete traceability from seedling cultivation to final shipping manifest, providing our OEM partners with a seamless market entry pathway.
Chengdu ChenLv Herb Co.,Ltd. was established in 2012 as a premier high-tech enterprise specializing in the research, development, cultivation, processing, and global export of botanical extracts and natural pharmaceutical active ingredients (APIs).

Browse Feed ExtractsThe primary clinical challenge with free Quercetin is its low oral bioavailability, which is caused by poor water solubility and rapid first-pass metabolism. Our technical roadmap focuses on developing delivery systems that improve absorption and efficacy.
Chengdu Chenlv Herb Co., Ltd. is investing in next-generation physical modification techniques. By reducing particle sizes to the sub-micron scale (micronization), we increase the surface area available for absorption. We are also collaborating with research institutes to develop phytosome complexes and liposomal encapsulation methods. These systems bind Quercetin to phospholipids, significantly improving transport across the intestinal barrier.
Our long-term development pipeline also includes biosynthetic extraction processes. By identifying and engineering specific enzymatic pathways, we aim to produce high-purity target flavonoids with a reduced carbon footprint, ensuring a sustainable, scalable supply of these compounds for global pharmaceutical markets.

Answers to technical and regulatory questions about OEM Quercetin and botanical extracts.
Our Quercetin is derived from high-quality Sophora japonica (Japanese Pagoda Tree) flower buds, which yield high concentrations of the natural precursor Rutin. This Rutin is then converted into premium Quercetin via controlled hydrolysis.
We supply standard Quercetin Dihydrate at pure assay values ≥95% and ≥98% as determined by HPLC analysis. Custom anhydrous and micronized options can be produced depending on project requirements.
We offer custom physical modifications, including jet-milling micronization to decrease particle size, as well as development pathways for phospholipid complexes (phytosomes) that enhance absorption across lipid membranes.
Every export shipment is accompanied by a batch Certificate of Analysis (COA), safety data sheets (SDS), non-irradiated declarations, BSE/TSE statements, and heavy metal testing profiles that meet USP and EP standards.
Our standard MOQ for standard catalog batches is 25 kg (typically packed in fiber drums). For custom formulations or micronized particles, the MOQ varies based on specific equipment parameters and raw material needs.
