Green tea extracts are herbal derivatives from green tea leaves containing various antioxidant ingredients. The biochemical properties of green tea extracts can be generally divided into four aspects such as, anti-oxidant, anti-carcinogen, anti-inflammatory, and anti-radiation. Green tea extracts exhibit stronger anti-oxidant protection for the human body than vitamin C and vitamin E. Scavenging effect of lipid free-radicals of polyphenols in green tea extracts can be clearly observed in experiments. The ability of GTP in green tea extracts to eliminate lipid-derived free radicals is noticeably stronger than that of ginkgo biloba extracts.
