Featured Standardized Extracts & Bioactives
High-potency botanical actives refined via continuous precision chromatography, full batch traceability, and verified analytical testing.
Industrial Extraction & Bioactive Standardization of Camellia sinensis
Deploying precision engineering to isolate Polyphenols, Catechins, and Epigallocatechin Gallate (EGCG) without toxic residual solvents or thermal degradation.
Continuous Countercurrent Solid-Liquid Extraction
Traditional static batch extraction often leads to thermal degradation of polyphenolic catechins. Our partner facilities adopt dynamic multi-stage continuous countercurrent extraction columns. Operating under moderate temperatures (45°C - 55°C) with USP-grade food ethanol/water mixtures, this protocol preserves sensitive stereocenters while delivering extraction yields exceeding 94% of native leaf polyphenols.
Polymeric Macroporous Resin Adsorption & Separation
To produce custom fractions—ranging from balanced 50% polyphenols up to high-potency 98% EGCG isolates—we utilize FDA-compliant non-polar and weakly polar synthetic polymeric resins. This chromatographic process separates caffeine, epigallocatechin (EGC), epicatechin gallate (ECG), and EGCG with extreme accuracy, while enabling continuous recycling and closed-loop solvent regeneration.
Supercritical Fluid Decaffeination Technology
Meeting the booming demand for stimulant-free functional nutrition, our decaffeinated lines undergo dense-phase Supercritical CO2 or selective resin adsorption. This reduces residual caffeine to below 0.5% (or <0.1% on demand) while maintaining total catechin purity, completely bypassing neurotoxic solvents like dichloromethane (methylene chloride) or ethyl acetate commonly found in commodity supply chains.

| Pure EGCG Isolate | ≥ 98.0% | ≥ 95.0% | ≥ 90.0% - 98.0% | ≤ 0.1% Ultra-Low | Cellular Longevity Supplements, Clinical Research Trials |
| L-Theanine Enhanced Complex | ≥ 40.0% | ≥ 25.0% | ≥ 10.0% | ≤ 2.0% | Nootropics, Cognitive Support Blends, Stress Relief Foods |
China Factory 4.0: Supply Chain Resilience & Scale
Integrating sustainable agricultural provenance from the highlands of Sichuan, Guizhou, and Zhejiang with fully automated processing arrays and predictive logistics.
GAP Seed-to-Silo Provenance
Direct contract farming over 15,000 hectares of high-altitude tea plantations guarantees non-GMO cultivars. Comprehensive agricultural audits eliminate pesticide runoff and ensure compliance with strict European and American maximum residue limits (MRLs).
SCADA Clean-in-Place Automation
Smart processing lines monitor temperature, flow rate, evaporation vacuum, and spray drying atomization in real time. Automated CIP systems prevent cross-contamination and guarantee lot-to-lot physical consistency across annual production capacities surpassing 3,000 metric tons.
D2D Strategic Buffer Stocks
By synchronizing ERP systems with major logistics hubs in Shanghai, Ningbo, and Shenzhen, we maintain dedicated safety stocks of core standardized actives. This shields enterprise brand partners from raw botanical seasonality and volatile oceanic shipping disruptions.
Green Chemistry & Zero Waste
Extracted tea bio-waste is reclaimed for organic composting, biomass boiler fuel, and natural dietary fiber isolation. 95% of extraction solvents are regenerated via low-pressure thermal recompression distillation, significantly reducing carbon footprints.
Macro-Industry Formulation Solutions
Engineered physicochemical characteristics tailored to the formulation limits of dietary brands, functional food technologists, and dermocosmetic scientists.
Nutraceuticals & Dietary Supplements
Our green tea powders are engineered with high bulk density (0.45 - 0.65 g/mL) and uniform particle sizing (80 to 120 mesh), making them directly compressible for high-speed tableting and hard-shell encapsulation. Free-flowing properties reduce excipient requirements, boosting active payload density in metabolic, mitochondrial, and cardio-health formulas.
RTD Beverages & Instant Functional Foods
Unrefined tea extracts cause turbidity, bitter astringency, and polyphenol-protein precipitation in liquids. We produce specialized clear-soluble grades treated with membrane filtration and micro-de-bittering enzyme treatments. These powders dissolve rapidly in cold water (down to 4°C), remaining crystal-clear without sedimentation over extended shelf lives.
Clinical Dermocosmetics & Skincare
Polyphenols oxidized upon air contact often darken skincare lotions. Our cosmetic-grade EGCG (>90% and >95%) features stabilized anti-browning crystal morphology with ultra-low trace heavy metals. It serves as an ultra-pure free-radical scavenger, offering proven photoprotection, sebum regulation, and matrix metalloproteinase (MMP) inhibition in anti-aging creams.
Localized Regulatory Support & Pharmacopeial Alignment
Navigating complex international botanical compliance with batch-specific dossiers verified by independent chromatography and high-resolution spectroscopy.
USP & Ph. Eur. Monograph Compliance
Our analytical protocols follow the exact standards of the United States Pharmacopeia (USP) and European Pharmacopoeia (Ph. Eur.). We cross-verify catechin distributions, identify potential adulterants like synthetic polyphenols via HPLC finger-printing, and validate marker retention through real-time stability chambers.
Strict Contaminant Screening Matrix
Every single batch undergoes testing for over 450 distinct pesticide markers using GC-MS/MS and LC-MS/MS. Heavy metals (Lead, Arsenic, Cadmium, Mercury) are strictly quantified via ICP-MS to comply with California Proposition 65 limits, alongside assays for Polycyclic Aromatic Hydrocarbons (PAH4) and Aflatoxins (B1, B2, G1, G2).
Complete Regulatory Dossiers
We provide full documentation packages for corporate vendor onboarding: Certificate of Analysis (COA), Allergen Free Statements, Non-GMO Project declarations, Irradiation-Free proofs, Kosher and Halal certifications, SDS, Flow Charts, and technical statements regarding EFSA safety thresholds for (-)-epigallocatechin-3-gallate intake.
Technical Roadmap & Next-Generation Phyto-Science
Pioneering liposomal delivery systems, co-crystal matrices, and bio-fermentation synergies to overcome oral bioavailability barriers.
Phytosome & Liposomal Encapsulation
Native EGCG suffers from low oral bioavailability due to intestinal oxidation and rapid glucuronidation. Our R&D team is scaling liposomal and phosphatidylcholine-bound complexes (Phytosomes). This patented encapsulation protects catechins through stomach acids, increasing biological plasma uptake by up to 300% without triggering gastric discomfort.
Enzymatic Glucosylation for Solubility
By coupling tea catechins with natural glucose moieties via safe cyclodextrin glucanotransferase enzymes, we create next-gen alpha-glucosyl-catechins. These offer up to 40 times higher water stability, total resistance to UV degradation, and neutral taste profiles suited for functional clear waters and clinical nutricosmetics.
Microbiome-Mediated Fermentation
Mirroring ancient micro-fermented tea traditions through modern bio-reactors, our emerging bioconversion platform utilizes selected probiotic consortia. This breaks down bulky gallate esters into small-molecule bio-assimilable metabolites (such as valerolactones), bypassing gut dysbiosis limitations in human wellness.
