METHOD OF EXTRACTING SELECTED SWEET GLYCOSIDES FROM THE STEVIA REBAUDIANA PLANT |
摘要 |
Individual sweet glycosides are obtained from the stevia rebaudiana plant. A mixture of sweet glycosides extracted from the stevia rebaudiana plant are processed to remove impurities by using two ion exchange columns. After removing the mixed sweet glycosides from the second column with methanol the solution is dried. Upon refluxing t he dried solids in a methanol solution and then cooling the solution, Stevioside precipitates out. The filtrate is further concentrated and cooled to precipitate out Rebaudioside A. This Rebaudioside A can be further purified as can the previously obtained Stevioside.
