Extraction of Mogrosides by using Flash extraction technique

The flash extract method was more effective for mogrosides extraction by comparing extract efficiencies of ultrasonic method,microwave method,and flash method.Flash extraction conditions were determined by an orthogonal test design,and the optimum extraction conditions were as follows:added 20 times water and extracted for 4 min at room temperature with 6000 r/min.In these conditions,the extraction efficiency of mogrosides was 10.057%,which indicated that the flash extraction was an efficient and low-cost method.
