Method for preparing rebaudioside C

The invention relates to a method for preparing high-purity stevioside rebaudioside RC, and belongs to the technical field of food additives. In the method, stevioside is used as a raw material, rebaudioside RC content in the raw material is about between 3 and 15 percent, and recrystallization technology and column chromatography technology are combined. The method comprises the following steps of: performing recrystallization by dissolving the stevioside which serves as the raw material in methanol; stirring and crystallizing at the temperature of 4 DEG C for 24 to 48 hours; recovering a solvent from crystallization mother liquor under reduced pressure to obtain a concentrate; performing silica gel column chromatography on the concentrate under the conditions that a stationary phase is silica gel with particle size of between 200 and 300 meshes, the weight of the silica gel mixed with a sample is 2.5 times that of the concentrate and the mass of pure silica gel is 20 to 50 times that of the concentrate; performing elution by using a mixed solvent system of trichloromethane and ethanol in the ratio of 2 to 1 or dichloromethane and ethanol in the ratio of 2 to 1, wherein water content in the ethanol is 2 to 10 percent; and collecting rebaudioside RC-containing main section eluent, mixing, concentrating, drying, detecting and packaging. By the method, a rebaudioside C product with purity of more than 95 percent can be obtained; and the method has a simple process and is suitable for large-scale industrial production.
