What Is EGCG Powder?
Epigallocatechin gallate (EGCG), with the molecular formula C₂₂H₁₈O₁₁, is the most abundant and bioactive catechin found in green tea. As a key component of green tea polyphenols, EGCG is a naturally occurring flavonoid renowned for its wide-ranging health-promoting properties. Isolated from Camellia sinensis, this compound demonstrates potent antibacterial, antiviral, antioxidant, anti-arteriosclerotic, anti-thrombotic, anti-angiogenic, anti-inflammatory, and anti-tumor activities.

Function
EGCG exhibits significant anti-tumor activity by modulating multiple molecular signaling pathways. It suppresses tumor development through inhibition of key cellular regulators, including nuclear factor kappa-B (NF-κB), mitogen-activated protein kinase (MAPK), epidermal growth factor receptor (EGFR), insulin-like growth factor (IGF), and cyclooxygenase-2 (COX-2). Additionally, EGCG helps prevent tumor metastasis by downregulating angiogenesis and extracellular matrix degradation via suppression of vascular endothelial growth factor (VEGF), matrix metalloproteinases (MMPs), and urokinase-type plasminogen activator (uPA) pathways.
Application
Epigallocatechin gallate (EGCG) is a well-documented cancer-inhibiting compound derived from green tea. It has been shown to influence the proteolytic processing of amyloid precursor protein, reducing the formation of amyloid-β peptides and amyloid plaques in preclinical mouse models. These properties support its potential role in cognitive health and neuroprotection.
