English Product Overview

Product Name: Green Tea Extract (Tea Polyphenols / Catechins Standardized, EGCG Marker)

Brand: staherb® – Changsha Sunho Biological Co., Ltd.

CAS No.: Tea Polyphenols blend 84650-60-2; EGCG 989-51-5｜EGCG Formula / MW: C₂₂H₁₈O₁₁ / 458.37

Botanical Source: Untreated (non-fermented) tender leaves of Camellia sinensis(L.) O. Kuntze (spring tea, one-bud-two-leaf, pan-fired 230–280℃ or steamed 100℃ for tens of seconds to inactivate PPO), mainly from Zhejiang/Hunan/Yunnan/Fujian pesticide-free or organic tea gardens.

• Product Introduction: Green Tea Extract is a standardized extract of tea polyphenols (flavan-3-ol catechins) from unfermented tea, where EGCG (Epigallocatechin-3-O-gallate) constitutes 50%–80% of total green tea catechins and serves as the principal material basis for antioxidation, metabolic regulation, and anti-inflammation. STAHBIO adopts low-temp hot-water / 60%–80% EtOH extraction → macroporous resin de-sugaring/de-amino → EtOH gradient elution → membrane/separation chromatography → low-temp vacuum drying to supply total polyphenols (UV-GAE) 50%/70%/80%/90%/98%, total catechins (HPLC) 30%–98%, EGCG 20%/40%/60%/80%/90%/98% standardized powders, plus decaffeinated grades (Caffeine ≤0.5%/1%/2%), high-theanine grades (L-Theanine 2%–5%), and EGCG ≥95%/98% high-purity monomers, with phospholipid complex / cyclodextrin inclusion / microencapsulation water-soluble options.

• Specifications & Appearance:

• Standardized extract: Light yellow to brownish-yellow fine powder (lighter at higher polyphenol), hygroscopic, weakly acidic aqueous solution (stable pH 4–6);

• High-purity EGCG monomer: White to off-white crystalline powder (mp 222–224℃), freely soluble in hot water/EtOH/MeOH/DMSO, slightly soluble in cold water;

• Stability & Storage: Extremely sensitive to light/heat/oxygen/alkali; >80℃ prolonged or pH>7 promotes EGCG→GCG epimerization and oxidative browning; finished goods nitrogen-flushed foil, light-protected, 2–8℃ or -20℃, powder stable 18–24 mo.

• Core Properties: EGCG with 8 phenolic OH groups shows antioxidant capacity ~100× VC, ~25× VE; synergizing with ECG/EGC/EC and theanine, it delivers potent antioxidation (Nrf2 activation), anti-inflammation (NF-κB inhibition), lipid/glucose modulation, thermogenic metabolic support, cardiovascular endothelial protection, neuroprotection, anti-photoaging and sebum control; theanine antagonizes caffeine anxiety and induces α-waves.

• Applications: Antioxidant/cardiovascular/metabolic-management nutraceuticals (capsules/tablets), weight-management thermogenesis blends (with caffeine/L-carnitine/CLA), functional beverages & solid drinks, anti-aging/anti-photoaging skincare/sunscreen/acne care, oral care (antibacterial/deodorizing), natural food antioxidant (oils/meat/bakery), feed antioxidant/immunity booster, pharma R&D & HPLC reference.

• Product Advantages: STAHBIO operates GMP workshops with HPLC center (UV@274nm split-peak EGCG/ECG/EGC/EC + Caffeine@273nm + Theanine@210nm) enforcing end-to-end quality from tea-garden base contracting → fixation-enzyme-inactivation fast test (TP≥22% DW, EGCG≥11% DW) → low-temp extraction → split-peak standardization → nitrogen-flush packing. Certified with ISO9001/22000(HACCP)/GMP/HALAL/KOSHER/Non-GMO; assists FDA GRAS / EFSA / NMPA health-food & cosmetic new-ingredient dossiers with ORAC/DPPH data.

注 / Note：以上概述基于绿茶提取物（茶多酚/EGCG）的现代研究与行业实践；"茶多酚%"（UV-GAE）与"总儿茶素%"（HPLC 四峰和）是两个不同标定口径，EGCG% 必为前者子集。staherb 提供的是植物提取物/标化原料而非成品药品/保健品；高剂量 EGCG（>800 mg/日）有潜在肝酶异常与咖啡因协同风险，孕妇及服药人群须遵医；终端产品须符合目标市场监管与标签法规（NMPA 保健食品原料目录、FDA GRAS、EFSA 等）。

The overview is based on modern research and industrial practices of green tea extract (tea polyphenols/EGCG). "Total polyphenols %" (UV-GAE) and "total catechins %" (HPLC 4-peak sum) are two distinct calibration bases; EGCG% is necessarily a subset of the former. STAHBIO supplies plant extract/standardized raw materials, not finished drugs; high-dose EGCG (>800 mg/day) carries potential ALT/AST elevation and caffeine-synergy risk—finished products must comply with regional regulations.
