Abstract
PURPOSE: To collect high-purity stevioside, by treating an extracted concentrated solution of leaves of "Stevia" with a salt or a base of a specific metal or subjecting it to ion exchange resin treatment.
CONSTITUTION: An extracted solution of leaves of "stevia" with water or water- containing alcohol is concentrated to 10W50wt% solid content, to give a concentrated solution, to which a salt or a base of calcium, iron, or aluminum to give a deposit, which is removed. The remaining concentrated solution is adjusted to pH 5W7, and the prepared precipitate is removed to give an aqueous solution containing stevioside. The aqueous solution is passed through an acidic cation exchange resin and a basic anion exchange resin successively, and stevioside is obtained from the passed solution. In the operation, a water-soluble organic solvent, e.g., ethanol, acetone, etc. is dissolved in the solution having passed through the acidic cation exchange resin or an aqueous solution dissolving a water-soluble organic solvent is passed through the basic anion exchange resin through which the aqueous solution containing stevioside has passed, and the stevioside is obtained from the passed solution.
