Premium raw botanical materials and standardized extracts manufactured in state-of-the-art GMP facilities for global biological industries.
Hesperidin ($C_{28}H_{34}O_{15}$), a prominent flavanone glycoside abundant in citrus peels, represents a cornerstone in the global market for naturally-derived bioflavonoids. In the current bio-economy, hesperidin serves not only as a primary active dietary supplement ingredient but also as the indispensable precursor for synthesizing Diosmin and Neohesperidin Dihydrochalcone (NHDC). Its pharmaceutical value is primarily anchored in its venotonic, vasoprotective, and anti-inflammatory properties, making it a critical component of therapies targetting Chronic Venous Insufficiency (CVI), hemorrhoidal disease, and microvascular disorders.
As global regulatory frameworks shift away from synthetic colorants and additives toward botanical alternatives, the demand for standardized citrus extracts has grown significantly. Industrial scale users, specifically in Europe, North America, and the Asia-Pacific region, consume thousands of metric tons of hesperidin annually. Our advanced extraction methods facilitate consistent, large-scale supply to meet these requirements.
The industrial utility of Hesperidin has evolved from traditional health supplements into functional beverages, animal feed additives (supporting gut health in livestock), and skincare formulations utilizing its high antioxidant potential. The integration of high-pressure liquid chromatography (HPLC) testing protocols ensures that batch-to-batch consistency matches international pharmaceutical standards.
China commands the global supply chain for citrus-derived bioflavonoids, producing over 70% of the world’s bulk Hesperidin. This dominance is not simply a matter of scale, but the result of optimized agricultural sourcing, advanced separation technologies, and centralized transport logistics.
Our production facilities tap directly into China's vast citrus cultivation regions in Sichuan, Hunan, and Jiangxi. By utilizing green peel (Citrus reticulata) and bitter orange (Citrus aurantium L.) directly from local orchards, we secure low-cost, high-yield botanical raw materials. This eliminates long-distance transportation costs and prevents raw material degradation.
We implement automated alkaline extraction followed by acid precipitation. Through precise control of pH values, crystallization temperature, and solvent ratios, we optimize yield and purity. This reduces resource waste, lowering production costs.
Our factory setup integrates eco-friendly practices, recycling process water and utilizing natural citrus peel biomass for energy. This aligns with international standards for sustainable ingredient sourcing.
A leading plant extract manufacturer and exporter with over 20 years of research and production experience.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) is a China-based manufacturer and exporter of herbal extracts and derivatives, active for over 20 years. We operate at the intersection of research and development, production, and international sales.
TRB's product range includes standardized herbal extracts, natural sweeteners, nootropics, fruit & vegetable powders, essential oils, and bee products. Reflecting our focus on product quality and manufacturing standards, we were awarded the 2026 "Best Global Herbal Extract Provider 2026".
TRB currently operates three specialized manufacturing facilities: one for herbal extracts, one for bee products, and one for animal-derived extracts. In recent years, we have expanded our research into nootropic ingredients, brain health extracts, anti-aging solutions, and longevity compounds to serve modern wellness markets.
To meet the specific requirements of various industries, we produce Hesperidin in multiple specifications. Each grade undergoes verification for purity, particle size, heavy metals, and microbiological levels.
| Active Component / Specification | Assay Method | Primary Physical Form | Target Application Industry |
|---|---|---|---|
| Hesperidin 90% - 98% | HPLC / UV-Vis | Light Yellow Crystalline Powder | Pharmaceuticals & Venotonic Formulations (e.g., CVI medications) |
| Micronized Hesperidin (D90 < 10 μm) | Laser Diffraction | Ultra-fine Powder | High Bioavailability Supplements & Softgels |
| Methyl Hesperidin | HPLC | Soluble White Powder | Functional Beverages, Cosmeceuticals (Dark circles reduction) |
| Citrus Bioflavonoids Complex (50%-80%) | UV | Brownish-yellow Powder | Dietary Supplements, Immunity Formulas, Animal Feed Preservatives |
Hesperidin is formulated with Diosmin (typically in a 1:9 ratio) to create standardized vascular stabilizers. These formulations reduce capillary permeability and improve microcirculation in chronic venous diseases.
Combined with Vitamin C, hesperidin supports immune health and vascular structure. Its free-radical scavenging properties help protect cells from oxidative stress.
The global market for plant-based active ingredients is shifting toward cleaner extraction methodologies and verifiable supply chains. Three key developments shape the future of Hesperidin sourcing:
Standard Hesperidin has low solubility in water, which limits its absorption in the human body. Because of this, the demand for modified versions like Methyl Hesperidin and Hesperetin-7-O-glucoside is increasing. These forms offer improved solubility, making them suitable for ready-to-drink beverages and skin serums.
Buyers in regions like Europe and North America require complete documentation regarding pesticide residues, heavy metals, and solvent levels. Using advanced instrumentation, such as GC-MS and ICP-MS, our laboratories ensure all products meet European Pharmacopoeia (EP) and USP standards.
Modern extraction relies on clean technologies. Our facilities use green chemical practices, closed-loop extraction, and eco-friendly waste management to minimize environmental impact while maintaining product purity.
When sourcing botanical ingredients from China, establishing clear quality standards and delivery terms is critical for supply chain stability. We support international procurement processes with structured protocols:
Every shipment includes a Certificate of Analysis (COA), heavy metal profiles, pesticide residue reports, and allergen declarations. We also provide DMF (Drug Master Files) documentation to support pharmaceutical registrations.
Standard packaging features 25kg cardboard drums lined with double-layered polyethylene bags. Aluminum vacuum bags are available for moisture-sensitive products. We coordinate shipments from major ports like Shanghai, Ningbo, and Shenzhen to ensure timely delivery.
We work closely with customers' QA/QC departments to provide custom particle sizes, such as micronization down to D90 < 10 microns, supporting the formulation of tablets and softgels.
Technical and commercial answers to help clarify sourcing, testing, and applications.
From high-purity natural extracts to functional fruit powders, we supply standardized ingredients to global manufacturers.
