To provide: methods for purifying steviol glycosides, including Rebaudioside X (Reb X); sweeteners and sweetener-containing compositions containing Reb X; beverages containing the compositions; and methods of improving the flavor and/or temporal profile of sweetenable compositions.SOLUTION: A method for purifying Reb X comprises the steps of: a. passing a solution of steviol glycosides through a multi-column system including a plurality of columns packed with an adsorbent resin to provide at least one column having adsorbed steviol glycosides; and b. eluting fractions with high Reb X content from the at least one column having adsorbed steviol glycosides to provide an eluted solution with high Reb X content.SELECTED DRAWING: Figure 19 【課題】レバウジオシドＸ（ＲｅｂＸ）を含むステビオールグリコシドの精製方法、ＲｅｂＸを含有する甘味料及び甘味料入り組成物、該組成物を含む飲料、並びに、甘味付与可能な組成物の香味及び／または経時プロファイルを改善する方法の提供。【解決手段】ＲｅｂＸを精製するための方法であって、ａ．ステビオールグリコシド溶液を、吸着剤樹脂が充填された複数のカラムを含むマルチカラムシステムに通過させて、ステビオールグリコシドが吸着された少なくとも１つのカラムを提供するステップと、ｂ．前記ステビオールグリコシドが吸着された少なくとも１つのカラムから、高ＲｅｂＸ含量を有する画分を溶出させて、高ＲｅｂＸ含量を有する溶出溶液を提供するステップとを含む方法。【選択図】図１９
