Pomegranate extract, derived from the fruit peel, seeds, and juice of Punica granatum, represents one of the most therapeutically potent botanical agents in modern phytochemistry. Standardized primarily for its high concentration of polyphenols, particularly ellagitannins such as Punicalagins (anomer A and B) and monomeric Ellagic Acid, this botanical active has transitioned from a traditional wellness remedy to a cornerstone ingredient in pharmaceutical, functional food, and nutricosmetic formulations worldwide.
Punicalagins are water-soluble polyphenols with massive molecular structures. Upon consumption, they undergo metabolic conversion in the gut flora, transforming into Urolithins. Our standardized extraction ensures maximum bioavailability of these therapeutic macromolecules.
Ellagic acid acts as a powerful direct antioxidant and a cofactor in dermatological melanin inhibition. Nanjing Tong Rui Bio-Tech standardizes this active up to 90% via HPLC, guaranteeing batch-to-batch consistency and high structural integrity.
Recent longevity research has highlighted Pomegranate Extract as the premier natural source of Ellagitannins required for Urolithin A synthesis, triggering mitophagy (cellular clean-up) and supporting mitochondrial rejuvenation.
The global commercial demand for pomegranate extract is driven by its diverse mechanism of action. In cardiovascular health, it inhibits Low-Density Lipoprotein (LDL) oxidation and modulates Angiotensin-Converting Enzyme (ACE) activity. In cosmetic science, the extract's ability to down-regulate tyrosinase synthesis and suppress UV-induced cellular inflammation makes it a premium additive for anti-aging and skin-brightening lines. To meet these rigorous pharmaceutical and nutritional standards, sourcing from verified, technologically proficient manufacturing plants in China is essential for secure, resilient global supply chains.
For more than 20 years, Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has served as China’s leading manufacturer and exporter of herbal extracts and their functional derivatives. Operating at the intersection of phytochemistry, molecular biology, and international trade, TRB is a technology-based enterprise combining research and development, smart manufacturing, and strict international regulatory compliance.
Due to our rapid development, scientific research, and dedicated service in the plant extract sector over two decades, TRB was honored with the 2026 "Global Biotechnology and Life Sciences Award" as the ''Best Global Herbal Extract Provider 2026''.
TRB's product spectrum focuses on highly sought-after active ingredients, including Herbal extracts, Sweeteners, Nootropics, Vegetable & Fruit Juice powders, Essential oils, and Bee Products. Our research initiatives concentrate on anti-aging, longevity, and brain health matrices, supporting formulation scientists across five continents.
TRB operates three specialized production facilities: one dedicated to Herbal Extracts, one for Bee Products, and another specializing in Animal Extracts. These facilities feature automated closed-loop extraction lines, continuous counter-current extraction systems, and advanced membrane filtration technology designed to preserve thermolabile compounds.
To address the stringent requirements of global pharmaceutical and food safety bodies, our production loops are validated with comprehensive certifications, including: GMP, ISO, HACCP, ORGANIC (USDA & EU), FDA Registration, HALAL, and KOSHER Certificates.
By integrating smart manufacturing (Factory 4.0 paradigms), TRB achieves real-time monitoring of critical process parameters (temperature, pressure, flow rate, and solvent ratios). This ensures complete tracking from raw plant material (raw fruit sourcing) to the finalized packaged extract, minimizing environmental footprints while offering competitive wholesale pricing.
Pomegranate extract serves as a major ingredient in heart-health formulations. It helps maintain healthy systolic blood pressure, supports arterial flexibility, and prevents lipid peroxidation in high-stress populations.
Standardized Ellagic Acid inhibits tyrosinase activity, presenting a natural skin-brightening solution. The high concentration of polyphenols acts as a protective barrier against UV-induced collagen breakdown.
By providing rich quantities of Ellagitannins, the extract acts as a precursor for Urolithin A synthesis, enhancing muscle cell regeneration, physical endurance, and post-workout recovery curves.
B2B raw material purchasers face persistent issues, including solvent residue contamination, plasticizer leaching, heavy metal limits, and varying active ingredient concentrations. Nanjing Tong Rui Bio-Tech resolves these challenges through strict analytical verification. Our Quality Assurance laboratories are equipped with High-Performance Liquid Chromatography (HPLC) to verify active concentrations, Gas Chromatography-Mass Spectrometry (GC-MS) to check for pesticide residues, and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to ensure compliance with European Union and United States Pharmacopeia (USP) heavy metal standards.
We provide Pomegranate Extract standardized to different active markers depending on the final application. Our standard range includes Punicalagins 20%, 30%, and 40% (determined by HPLC, highly water-soluble), as well as Ellagic Acid 40%, 70%, and 90% (determined by HPLC, ideal for cosmetic formulations). Custom compound ratios can be engineered by our R&D team to meet specific client requirements.
Our extraction processes use food-grade water and ethanol exclusively; we avoid toxic solvents like methanol, benzene, or chlorinated hydrocarbons. All batches are tested to comply with USP <467> guidelines for organic volatile impurities. Heavy metals (Lead < 3.0 ppm, Arsenic < 1.0 ppm, Cadmium < 0.1 ppm, Mercury < 0.1 ppm) are verified using in-house ICP-MS systems before shipment.
Every shipment includes a detailed Certificate of Analysis (COA) specifying test methods, active marker percentages, particle size distribution, moisture levels, ash content, microbial count (total plate count, yeast & mold, E. coli, Salmonella), and heavy metal profiling. Upon request, we also provide technical documents such as MSDS, flow charts, allergen statements, GMO-free declarations, and irradiation-free statements.
Yes. Our high-grade Punicalagin water-soluble series is optimized for the functional beverage market. It dissolves quickly and completely in water at room temperature, producing a clear solution without precipitation or sediment. This makes it suitable for functional juices, ready-to-drink (RTD) teas, and liquid dietary supplement formulations.
Our Pomegranate Extract has a verified shelf life of 24 months from the manufacturing date, provided it is kept in its unopened original packaging. It should be stored in a cool, dry environment away from direct sunlight, moisture, and heat. The product is packed in food-grade double plastic bags inside fiber drums (25 kg/drum) to prevent moisture absorption.
Yes, we provide custom processing services. We can adjust the particle size (typically 80-100 mesh) to meet your formulation requirements for direct compression tableting or capsule filling. We also offer microencapsulation services to improve stability and mask the natural astringent taste of pomegranate polyphenols in powder applications.
