Summary:PROBLEM TO BE SOLVED: To produce a diglycosylated gallic acid derivative by an industrially simple operation in a high yield and in a high purity. SOLUTION: This method for producing the diglycosylated gallic acid derivative comprises performing a condensation reaction of gallic acid, a gallic acid ester or a gallic acid salt with an acetylated monosaccharide, disaccharide or oligosaccharide while distilling off acetic acid produced as a byproduct, and after the completion of the reaction, isolating the obtained diglycosylated gallic acid derivative by crystallization.
