Optimization of The Extraction Process of Polysaccharide from Schisandra Chinensis (Turcz.) Baill

Based on Box-Behnken response surface method, it utilizes ultrasound-microwave synergistic effect to extract polysaccharide of Schisandra chinensis by taking the polysaccharide extraction ratio of fructus schisandra. On the basis of designing single factor experiment, it selects the extraction temperature, microwave power, ultrasonic wave power, feed liquid ratio and reaction time as the review factors and further determines the optimal extraction process by the response surface method: the extraction temperature is 65°C; the microwave power is 550W; the ultrasonic wave power is 60W; the reaction time is 15min; the feed liquid ratio is 1:25; under such condition, the polysaccharide extraction ratio is 13.23%.
