摘要
A series of porous resins (PYR) with different content of pyridyl group were prepared,and their physical structure and adsorption properties on the stevia glycosides werestudied in detail. Afler the selective adsorption of PYR resins, the rebaudioside A couldbe separated hem the other components of the stevia glycosides, and a new methodforobtaining pure rebaudioside A is reported.
