PROBLEM TO BE SOLVED: To provide a method for producing theasinensin, capable of obtaining the theasinensin more stably and in a higher yield than those of conventional methods, while being simple. SOLUTION: This theasinensin is produced by oxidizing epigallocatechin and/or epigallocatechin gallate in the presence of a non-homogeneous catalyst, and then reducing the obtained oxidation product, in a higher yield than those of the conventional methods.
