(-)-表没食子儿茶素没食子酸酯(EGCG):
        表没食子儿茶素没食子酸酯 (EGCG)是绿茶中最有效的抗氧化多酚,具有抗氧化、抗癌、抗突变等活性。EGCG具有特殊的立体化学结构和非常强的抗氧化活性,在抗肿瘤,抗突变,抗衰老,抗炎,抗病毒等方面有着出色的表现。此外,它也用作肿瘤多药耐药性的逆转剂,能够改善癌细胞对化疗的敏感性并减轻对心脏的毒性。   这些作用使EGCG具有非常广阔的应用前景和市场价值,本公司高纯度EGCG工艺近期取得突破性进展,大大降低了生产成本,故以绝对优势的价格面向客户,欢迎有意向的客户前来订购!
        EGCG is the major component of the polyphenolic fraction of green tea. It makes up about 10-50% of the total green tea catechins includeing epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate(ECG), epicatechin(EC), gallocatechin gallate (GCG), catechin are major catechin of green tea catechin. The antioxidant activity increased in the following order: EC-ECG-EGC-EGCG. Many studies indicate EGCG plays a role, which protects aganist free-radical DNA damage, protects aganist the effects of ionizing radiation and ultraviolet radiation, inhibits lipid peroxidation, decreases serum cholesterol levels, LDL, VLDL and triglycerides, interferes with the binding of cancer-causing agents to cellular DNA, helps to neutralize dietary carcinogens, works with enzymes and other antioxidants in the intestine, liver and lungs to prevent the activation of certain carcinogens before they damage DNA. As a free radicals scavenger, EGCG combats the effects of pollution, sunlight and smoking, helps skin from wrinkling and aging.
