The invention relates to the use of adsorb/desorb chromatography to prepare enriched compositions comprising rebaudioside B and/or rebaudioside D. Compositions with enriched rebaudioside-B and/or rebaudioside-D components may be prepared from Stevia-derived glycoside compositions using an adsorb-desorb chromatography process where the stationary phase of the chromatography bed comprises a macroporous neutral adsorbent resin.
