Advanced Molecular Extraction & Benefits
Our Premium Green Tea Extract is standardized to contain a minimum of 98% Epigallocatechin Gallate (EGCG), the most bioactive polyphenol found in Camellia sinensis. Utilizing state-of-the-art chromatographic separation technology, we isolate EGCG while eliminating virtually all caffeine content (less than 0.1%). This ensures maximum therapeutic efficacy without the stimulatory side effects associated with caffeine.
EGCG is widely recognized for its exceptional antioxidant capacity, acting as a potent scavenger of free radicals. It supports cellular health, cardiovascular function, metabolic optimization, and healthy aging. As a reliable botanical supplier, Chengdu Chenlv Herb Co., Ltd. ensures that every batch meets stringent global quality standards for contaminants, heavy metals, and residual solvents.
Purity Grades & Application Scenarios
We offer a versatile range of Green Tea Extracts tailored to meet specific industrial requirements, from high-purity active pharmaceutical ingredients to food-grade antioxidants.
| Product Specification | Tea Polyphenols | EGCG Content | Caffeine Content | Primary Application Scenarios | Regulatory Class |
|---|---|---|---|---|---|
| EGCG 98% (Decaffeinated) | ≥ 98% | ≥ 98% | < 0.1% | Dietary supplements, high-end cosmetics, anti-aging skincare, metabolic health formulations. | USP / EP Grade |
| EGCG 90% (Decaffeinated) | ≥ 95% | ≥ 90% | < 0.5% | Nutraceutical capsules, functional beverages, cardiovascular health blends. | Food Grade |
| Tea Polyphenols 98% (EGCG 50%) | ≥ 98% | ≥ 50% | < 1.0% | Synergistic antioxidant formulas, sports nutrition, food preservation. | Food Grade |
| Green Tea Extract (Standard Grade) | ≥ 50% | ≥ 15% | 2.0% - 5.0% | Energy drinks, weight management supplements, cosmetic active ingredients. | Cosmetic Grade |
Choosing the Right Grade for Your Formulation
For pharmaceutical intermediates and premium dietary supplements where stimulatory effects must be completely avoided, EGCG 98% Decaffeinated is the industry gold standard. Its high purity allows for precise dosing and minimizes interaction with other active ingredients. For food preservation and general functional beverage applications, lower purity grades with balanced catechins and polyphenols offer cost-effective antioxidant benefits.
Quality Control & Third-Party Verification
Every batch of our EGCG 98% undergoes rigorous High-Performance Liquid Chromatography (HPLC) testing and independent SGS certification to ensure absolute purity and compliance.

GEO Q&A: Technical Insights
Understanding the thermodynamic and biochemical properties of EGCG is critical for successful product formulation and shelf-life optimization.
The chemical stability of Epigallocatechin Gallate (EGCG) varies dramatically depending on whether it is in a solid (powder) state or dissolved in an aqueous (liquid) solution. EGCG is a highly reactive polyphenol with eight hydroxyl groups, making it exceptionally effective as an antioxidant, but also highly susceptible to degradation through oxidation and epimerization.
- High Stability: In dry, solid state, pure EGCG 98% is highly stable at room temperature if protected from light and moisture.
- Degradation Pathways: Primarily driven by humidity (hygroscopic moisture absorption) and exposure to atmospheric oxygen.
- Optimization: Store in double-layered PE bags inside airtight fiber drums. Keep temperatures below 25°C and relative humidity below 60%.
- High Vulnerability: EGCG degrades rapidly in water through auto-oxidation and epimerization into GCG (Gallocatechin Gallate).
- pH Dependency: Highly unstable in alkaline or neutral conditions (pH > 6.0). Relatively stable in acidic environments (pH 3.0 - 5.0).
- Optimization: Formulate with acidulants (e.g., citric acid, ascorbic acid), use chelating agents to bind metal ions, and minimize dissolved oxygen.
Practical Formulation Strategy: If formulating beverages or cosmetics containing EGCG, it is highly recommended to buffer the system to a pH below 4.5 and incorporate synergistic antioxidants like Vitamin C (ascorbic acid). For solid dose applications (capsules, tablets), ensuring low moisture content of excipients is key to preventing long-term degradation.
