Standardized botanical extracts, pure plant monomers, and customized granulations engineered for immediate export to Kazakhstan, Almaty, Astana, and the broader EAEU economic zone.
Kazakhstan stands as the primary economic engine and pharmaceutical manufacturing hub of Central Asia. As a key member of the Eurasian Economic Union (EAEU), Kazakhstan’s dietary supplement, functional food, and phytopharmaceutical industries are experiencing an unprecedented surge in demand. Local formulators across major industrial zones in Almaty, Astana, Shymkent, and Karaganda are increasingly seeking robust, high-purity raw materials to fuel regional production.
Among active botanical monomers, Quercetin (CAS 117-39-5)—primarily derived from the flower buds of Sophora Japonica (Japanese Pagoda Tree)—has emerged as a foundational bioflavonoid. Driven by rigorous consumer awareness surrounding respiratory wellness, cardiovascular support, and seasonal immune resilience, the Kazakhstan market demands uncompromised physical quality, precise HPLC assays, and seamless regulatory customs clearance.
Importing botanical extracts into Kazakhstan requires strict adherence to Technical Regulations of the Customs Union (TR CU 021/2011 on Food Safety). Our export documentation includes full Certificate of State Registration (SGR) support files, heavy metal panels, and pesticide residue certificates validated by accredited testing bodies.
Leveraging China's proximity via the Khorgos Dry Port and the China-Europe Railway Express (Xi'an/Lianyungang to Almaty route), bulk Quercetin shipments achieve door-to-door delivery within 5 to 7 days, eliminating long ocean freight delays and high transit insurance costs.
To serve the demographic preferences of Central Asian end-users, our Quercetin Dihydrate and Anhydrous grades are certified 100% Halal, non-GMO, allergen-free, and processed without synthetic chemical carriers or toxic extraction solvents.
For R&D specialists and procurement managers in Kazakhstan’s pharmaceutical factories, selecting the correct chemical state of Quercetin is critical to formulation stability, dissolvability, and bioavailability. RAAG Biotech Co., Ltd. manufactures distinct product lines tailored to specific finished-dose delivery systems:
| Quercetin Grade / Specification | Active Assay (HPLC) | Solubility Profile | Primary Industrial Application | Kazakhstan Market Suitability |
|---|---|---|---|---|
| Quercetin Dihydrate 95% / 98% | ≥ 95.0% – 98.0% | Lipophilic; sparingly soluble in cold water | Standard Hard Gel Capsules, Tablets, Herbal Teas | High volume demand for economical daily immunity brands. |
| Quercetin Anhydrous 98% | ≥ 98.0% (Dry Basis) | Enhanced solubility in organic matrices & lipids | Softgels, Lipid-based Tinctures, Pharma Formulations | Ideal for high-density tablet compaction with low water activity. |
| Liposomal Quercetin Powder 50% | ≥ 50.0% Quercetin | Water-dispersible liposome complex | Premium Liquid Syrups, Effervescent Powders, Shots | Surging segment in Almaty premium pharmacy chains for high absorption. |
| Direct Compression (DC) Granular 95% | ≥ 95.0% | Free-flowing granules (40-80 Mesh) | High-Speed Direct Compression Tablet Lines | Eliminates wet granulation step, cutting manufacturing costs by 20%. |
| Wild Horsetail Derived Quercetin | Standardized Flavonoids | Plant-native synergetic matrix | Bone Strength & Joint Health Formulations | Combines silica with bioflavonoids for targeted osteo supplements. |
Unmodified Quercetin raw powder typically exhibits low aqueous solubility (approx. 0.01 mg/mL at 25°C), limiting intestinal absorption. To help Kazakh supplement brands achieve superior biological activity, RAAG Biotech has commercialized Liposomal Encapsulated Quercetin Powder (50%). Utilizing sunflower-derived phosphatidylcholine lecithin matrices, our liposomal structure protects the active polyphenol core from stomach acid degradation, yielding up to 5.7-fold higher blood plasma concentrations compared to standard unencapsulated powders.
Understanding regional epidemiology and lifestyle factors in Kazakhstan allows manufacturers to market targeted product formulations. High thermal variations between summer and severe steppe winters, urban environmental dust in industrial centers, and a dietary focus on protein-rich foods create targeted health needs:
Southern Kazakhstan experiences heavy spring pollen concentrations, leading to widespread allergic rhinitis. Quercetin acts as a natural mast cell stabilizer, inhibiting histamine release. Local pharmaceutical companies blend our 98% Quercetin Dihydrate with Vitamin C, Bromelain, and Zinc for potent anti-histamine capsule lines.
Cardiovascular care is a top healthcare priority across EAEU countries. Quercetin’s robust antioxidant capability reduces lipid peroxidation and supports nitric oxide synthesis in endothelial tissues. Formulations combining Quercetin Anhydrous with Coenzyme Q10 and Silybin Phospholipids are widely prescribed by health practitioners in Astana.
Demand for long-term immune modulation remains strong in urban clinical settings. Quercetin’s role as a zinc ionophore facilitates cellular zinc uptake, combating viral replication and cellular oxidative stress. Softgel manufacturers in Shymkent utilize our high-purity Sophora Japonica extracts for daily protective health packs.
Operating since 2014 from our state-of-the-art facility in the High-Tech Development Zone of Xi'an, China, RAAG Biotech Co., Ltd. is a dedicated phytopharmaceutical extraction house rather than a trading intermediary. Our operations are engineered around full material auditability, reproducible active yields, and clean-room handling.
Raw material purity begins in the field. We manage contracted agricultural bases for Sophora Japonica cultivation, enforcing strict controls over pesticide usage, soil heavy metals, and harvest timing to ensure peak quercetin flavonoid content before extraction.
Our quality control laboratory operates in-house High-Performance Liquid Chromatography (HPLC), Ultraviolet-Visible Spectroscopy (UV), Gas Chromatography (GC for solvent testing), and Atomic Absorption Spectrometry (AAS). Every lot is shipped with an authentic COA matching internal retention samples.
Our plant maintains full compliance with global regulatory standardizations: ISO 9001, HACCP, HALAL, KOSHER, and GMP audit protocols. Retained batch files permit rapid validation for international health department filings.
Direct technical and commercial answers for purchasing officers, QA directors, and contract manufacturers in Kazakhstan.
Every shipment is packed with a batch-specific Certificate of Analysis (COA via HPLC), MSDS, Certificate of Origin (Form A/CO), Packing List, Commercial Invoice, Technical Data Sheet (TDS), Non-GMO statement, and Heavy Metal/Microbiological Test Reports compliant with TR CU 021/2011.
Our standard MOQ for commercial Quercetin Dihydrate 98% and Anhydrous grades is 25 kg (packaged in standard food-grade fiber drums with double PE inner liners). Sample batches (1 kg to 5 kg) are readily available for analytical validation and pilot scale testing.
Rail freight originating from our Xi'an manufacturing hub transits through Khorgos directly to Almaty cargo stations in approximately 5 to 7 days, providing an optimal balance of low freight cost and high speed. Air express via Chengdu/Beijing reaches Astana in 2 to 4 days.
Yes. All Quercetin powders extracted from Sophora Japonica are certified Halal. They contain no animal derivatives, ethyl alcohol residue over international limits, or cross-contaminants, allowing seamless inclusion in Halal-certified consumer products.
Absolutely. We offer standard 80 Mesh powder, ultrafine 200 Mesh powder for suspension beverages, as well as customized Direct Compression (DC Grade) 40-80 Mesh granules that improve flowability and prevent capping in high-speed tablet presses.
Our Quercetin is double-sealed in moisture-barrier aluminum foil bags inside heavy-duty fiber drums. When stored in a cool, dry warehouse away from direct sunlight at temperatures below 25°C, the product maintains a stable 24-month shelf life without degradation or moisture caking.
