A functional microbially fermented tea extract containing a novel polyphenol derivative and a method for producing the same are provided. A functional microbially fermented tea extract containing various extracts and a novel polyphenol derivative is produced by subjecting, to an extraction treatment, a microbially fermented tea leaf obtained by culturing one species selected fromsp. (PK-1),(NBRS 4214) sp. (AO-1),(NBRS 4122) sp. (SK-1), andsp. (KA-1) with a tea leaf. Furthermore, for example, a functional fermented tea extract enriched with a novel polyphenol derivative is produced.

Method for producing functional microbially fermented tea extract containing polyphenol derivative

A novel substance exhibiting physiologically active effects is produced from a tea leaf. A novel polyphenol derivative is produced, for example, by subjecting a microbially fermented tea leaf obtained by culturingsp. (PK-1) with a tea leaf, to an extraction treatment.
