摘要：
Exemplary embodiments of this invention encompass a method for purifying crude rebaudioside A. In particular, this invention relates to a method for purifying crude rebaudioside A compositions comprising purities from approximately 40 % to approximately 95 % rebaudioside A to obtain a substantially pure rebaudioside A product with a single crystallization step. Resulting polymorph and amorphous forms of rebaudioside A and methods for preparing polymorph and amorphous forms of rebaudioside A from crude rebaudioside A compositions and substantially pure rebaudioside A compositions also are disclosed.本發明之示範性實施態樣包含一種純化粗甜菊糖雙苷A之方法。具體來說,此發明關於一種用於純化包含自約40%至約95%甜菊糖雙苷A純度之粗甜菊糖雙苷A組成物以自單一結晶步驟得到實質上純的甜菊糖雙苷A產物之方法。本發明亦揭示所形成之多晶型及非晶型之甜菊糖雙苷A及自粗甜菊糖雙苷A組成物及實質上純的甜菊糖雙苷A組成物製備多晶型及非晶型之甜菊糖雙苷A之方法。
