Abstract
Glycosides such as stevioside, glycyrrhizin and neohesperidin dihydrochalcone are separated from non-glycosides such as phyllodulcin and perillartine by column chromatography using a porous gel.
Claims7
A method of resolving glycoside and non-glycoside sweet components having a molecular weight ranging from 250 to 1,000 in a natural sweet extract, which comprises:
- passing a solution of said natural sweet extract over a column of a porous organic gel having a pore diameter sufficient to achieve the desired resolution which is less than 1.times.10.sup.4 A and eluting the resolved glycoside and non-glycoside components from said gel with an eluant.
