<P>PROBLEM TO BE SOLVED: To provide a method for selectively reducing the amount of polyphenols from a tobacco material by a simple treatment process, namely, capable of treating a greater amount of tobacco extract through sustaining the adsorbing effect of a polyvinyl polypyrrolidone resin, and to provide a tobacco material decreased in polyphenols. Ž<P>SOLUTION: The method for reducing the amount of polyphenols from a tobacco material includes (a) a step of extracting a tobacco material with an aqueous solvent to separate the tobacco material into a water-soluble tobacco extract and tobacco residues, (b) a step of removing the polyphenols from the water-soluble tobacco extract by conducting such a column method as to pass the water-soluble tobacco extract through a column packed with a polyvinyl polypyrrolidone resin, and (c) a step of adding the resultant water-soluble tobacco extract decreased in the polyphenols prepared by the step (b) to the tobacco residues of the step (a).
