Preparation of productive and highly purified mogrosides from Siraitia grosvenorii

The mogrosides of Siraitia grosvenorii are natural sweetener and potential chemopreventive agents. In order to obtain high-yield and good-quality mogrosides, the flash extraction method was employed to extract mogrosides from S. grosvenorii . The extraction parameters were optimized by Taguchi’s experimental design, and the total yield of mogrosides was 8.6% under the optimum conditions. After purification by the chromatography column, the purity of mogrosides was greater than 92%. The separation technique described here may be applicable to commercial production of high-quality mogrosides.
