Abstract

The present invention provides methods to treat mixtures containing natural rebaudioside A (Reb A), rebaudioside B (Reb B), and rebaudioside D (Reb D), synthetic counterparts of these, and/or derivatives of the natural or synthetic embodiments obtain one or more of these glycosides in more pure form. In many embodiments, the invention can be used to process glycoside mixtures obtained at least in part from natural sources such as the Stevia plant. This allows, for instance, the recovery of a product including Reb A material in more pure form relative to Reb B material or Reb D material. As an alternative or in addition to recovery of the purified Reb A material, a product including Reb B material and/or Reb D material in more pure form relative to Reb A material can be obtained.
