摘要：
The present invention relates to the preparation of novel polyphenol fractions of Camellia sinensis (tea), the use thereof and formulations containing them. The invention relates specifically to the preparation of extracts deprived of caffeine but containing the polyphenols deriving from epigallocatechin in a natural ratio. The use of these novel extracts, alone or in combination with other active principles, is of interest to the food, pharmaceutical, and cosmetic industry, especially to treat cytotoxic and oxidative conditions.
