| Abstract: | In order to obtain pure rebaudioside A, the condition for separating rebaudiosidc A from stevioside by recrystallization in methanol, 2-propanol and water was studied. By concentrating the mother liquor of stevia glycosides after the separation of stevioside, a sugar containing 98 % rebaudioside A was obtained. Its melting point was determined, and the HPLC was performed. |
