        Depend on our compny's technology.We can extract the high content EGCG monomer from green tea. Regular consumption of tea has been associated with reduced risk of several forms of cancer and other health benefits according to some epidemiological studies. Tea leaves contain many constituents,and the biological effects of tea areoften attributed to the polyphenols among the tea constituents.In freshly harvested tea leaves, the following flavanols,known collectively as the catechins, are present:(+)-catechins,(+)-gallocatechin,(-)-epicatechins,(-)-epicatechins-3-gallate,and (-)-epigallocatechin-3-gallate(EGCG),the main ingredient of green tea extracts,has been shown to inhibit growth in a number of tumor cell lines such as human leukemia cell lines, mouse NFS60 cell line,MCF-7 breast carcinoma, HT-29 colon carcinoma, A-427 lung carcinoma.UACC-375 melanoma, the prostate cancer cell lines LNCaP, PC-3 and DU145,leukemia blast cells from AML patients,and human epidermoid carcinoma cell line A431, in 1996, The Division of Cancer Prevention and Control,National Cancer Institute of the United States, Published a clinical development plan with respect to tea. At the present time,EGCG can be obtained by isolation from green tea extracts,and the yield depends on the processing and the source of the tea.Now EGCG monomer can be an anticancer agent.
