The commercial preparation of Polyphenon E contains about 3% (-)-epigallocatechin as an impurity.
Approval Year
Sample Use Guides
In a clinical trial, patients were given 1, 2, 3 or 4 capsules (1 capsule contains 37 mg (-)-epigallocatechin).
Route of Administration:
Oral
In a cell growth assay, human tumor cell lines MCF-7, SF-268, HCT-116 and NCI-H460 were treated with 100, 50, 25, 12.5, and 6.25 uM of (-)-epigallocatechin for 48 h. At concentration of 50 uM, the drug gave 50%, 10%, 60% and 40% inhibition of growth of breast, CNS, colon, and lung cancer cells, respectively.
