영문 초록

Green tea and black tea are commonly drunk in the Asian and Western countries. It is known that the major tea catechins, (-)-epicatechin, (-)-epigallocatechin, (-)-epigallocatechin gallate, and (-)-epicatechin gallate are epimerized by fermentation processing. In this study, the effects of the extracts of the non-fermented and fermented teas on hepatic fibrosis were examined by means of the in vitro collagen secretion and collagen promoter assay. As a result, the treatment with green tea extract was found to reduce the secretion of collagen into the media, whereas black tea extract increased it, in the human hepatic stellate cell line.
