摘要：
1. The method of cleaning Reb X, including: a. passing a solution of steviol glycosides through a multi-column system comprising several columns filled with an absorbent resin, to obtain at least one column with adsorbed steviol glycosides； and b. eluting fractions with a high Reb X content from at least one column with adsorbed steviol glycosides to obtain an eluted solution with a high Reb X.2 content. The method of claim 1, further comprising the steps of: a. removing alcohol solvents from the eluted solution to obtain a mixture with a high Reb X content； and b. further concentrating the mixture with a high Reb X content to obtain a mixture with a high Reb X content containing from about 30% to about 40% solids. 3. The method according to claim 1, further comprising removing impurities from the multi-column system before step (b). The method of claim 1, further comprising: a. discoloration of the high Reb X eluted solution to give a first adsorption solution b. removing the alcohol solvent from the first adsorption solution and passing the remaining solution through a column of large-pore adsorbent to obtain a second adsorption solution； c. deionization of the second adsorption solution. 5. The method according to claim 4, characterized in that the alcohol solvent is removed from the second adsorption solution to obtain a mixture with a high Reb X content containing from about 30% to about 40% solids. The method according to claim 4, further comprising completely removing the solvent from the second adsorption solution to obtain a dry powder with a high Reb X.7 content. The method according to claim 1, characterized in that1.
