Introduction

For millennia, green tea (Camellia sinensis) has been cherished in traditional Asian wellness practices for its invigorating and health-promoting properties. Modern scientific research has validated its value, identifying polyphenols—especially EGCG—as the core active components that unlock remarkable potential in health support, beauty care, and beyond. As a leading plant extract manufacturer, Hangzhou Greensky Biological Tech.Co.,Ltd delivers high-quality Green Tea Extract to global industries, bringing nature’s goodness to your products.

Part 1: What is Green Tea Extract?

Plant Introduction

Latin Name: Camellia sinensis (L.) O. Ktze.

Source Plant: An evergreen shrub belonging to the Theaceae family, native to China and now widely cultivated in Japan, India, Sri Lanka, and other subtropical regions.

Key Growing Regions: Premium sources include Zhejiang, Fujian, and Anhui provinces in China, known for ideal soil and climate conditions.

Extraction Part

The extract is derived from the young leaves and buds of Camellia sinensis, which are rich in bioactive compounds before oxidation.

Active Components

The primary active ingredients are tea polyphenols, a group of flavonoids including Epigallocatechin Gallate (EGCG), Epigallocatechin (EGC), Epicatechin Gallate (ECG), and Epicatechin (EC). EGCG is the most abundant and biologically active component, accounting for 50-60% of total polyphenols.

Standardized Specifications

We offer flexible specifications to meet diverse needs:

Green Tea Extract 50% Polyphenols (UV detection)

Green Tea Extract 30% EGCG (HPLC detection)

Low-caffeine or decaffeinated versions (≤0.1% caffeine)

Water-soluble and oil-soluble formulations for different applications.

We also offer green tea extracts with varying levels of L-theanine.

Test Reports

Every batch comes with a comprehensive Certificate of Analysis (COA), including test results for polyphenol/EGCG/L-Theanine content, caffeine level, heavy metals (Pb, Cd, Hg), pesticide residues, and microbial contaminants (total aerobic bacteria, mold, yeast).

Part 2: Key Health Benefits and Mechanisms of Action

Green Tea Extract’s benefits are backed by extensive scientific research, with mechanisms rooted in its bioactive compounds:

Antioxidant Protection: EGCG scavenges free radicals (e.g., reactive oxygen species) more effectively than vitamin C or E, protecting cells from oxidative damage. It enhances the activity of endogenous antioxidant enzymes like superoxide dismutase (SOD).

Anti-Inflammatory Effects: Inhibits the production of pro-inflammatory cytokines (TNF-α, IL-6) and enzymes (COX-2, iNOS), reducing chronic inflammation linked to metabolic and cardiovascular issues.

Metabolic Support: Promotes fat oxidation and boosts thermogenesis by activating AMP-activated protein kinase (AMPK), aiding in healthy weight management.

Cardiovascular Health: Lowers LDL cholesterol oxidation and improves endothelial function, supporting healthy blood pressure and lipid profiles.

Skin Protective Effects: Neutralizes UV-induced free radicals, inhibits collagenase activity, and reduces melanin synthesis, offering anti-aging and brightening benefits.

Part 3: Wide-Ranging Application Industries

Our premium Green Tea Extract is a versatile ingredient for multiple sectors:

Dietary Supplements & Nutraceuticals: Used in capsules, tablets, and softgels targeting antioxidant support, metabolic health, and cardiovascular wellness.

Functional Foods & Beverages: Added to bottled teas, energy drinks, protein bars, and probiotic products to enhance nutritional value and extend shelf life.

Cosmetics & Personal Care: Featured in serums, creams, masks, and sunscreens for anti-aging, soothing sensitive skin, and brightening complexions.

Animal Nutrition: Incorporated into feed additives for poultry, livestock, and aquatic animals to improve immunity and reduce oxidative stress.

Part 4: How to Choose a High-Quality Green Tea Extract

Selecting a reliable supplier ensures product efficacy and safety. Focus on these key factors:

Standardization & Purity: Prioritize extracts with clearly labeled polyphenol/EGCG content (tested via HPLC/UV) to guarantee consistent performance.

Advanced Extraction Technology: Opt for suppliers using gentle extraction methods (e.g., water extraction, low-temperature concentration) to preserve bioactive compounds. We adopt membrane separation and spray-drying technology for maximum potency.

Third-Party Testing: Verify compliance with international standards through independent lab reports for heavy metals, pesticides, and microbial contaminants.

Certification lored specifications (polyphenol/EGCG content, caffeine level, solubility) and formulations to match your product development goals.

Stable Supply & Competitive Pricing: Direct cooperation with tea plantations and efficient production lines ensures consistent supply and cost-effective pricing.

Professional Technical Support: Our R&D team provides technical data, formulation advice, and application solutions to help you integrate the extract seamlessly.

Green Tea Extract, with its potent polyphenols and versatile benefits, is a valuable addition to health, food, and beauty products. Choosing a high-quality source ensures you deliver maximum value to your end-users.
