In this paper, the preparation process of Stevioside and Rebaudioside A sample of high-purity extracted from Stevia rebaudiana Bertoni. has been introduced. Stevioside and Rebaudioside A has been extracted from Stevia rebaudiana Bertoni. with water first, and then separated by the process of flocculation using Ferrous sulfate, adsorption using HPD-X macroporous resin, desalination and decolorization using series of D001 and D201 ion exchange resin, and recrystallization using methanol, and then the total purity of the sample of Stevioside and Rebaudioside A can reach 98%.
