| Abstract: | On the basis of single factor experiments, the ultrasonic extraction process of polysaccharide from Sedum Aizoom L. was studied by orthogonal experimental method. Ultrasonic temperature, solid-liquid ratio, ultrasonic time, extraction times were discussed on the polysaccharide extraction effect. The results show that the order of the various factors influence respectively ： extraction times, solid-liquid ratio, ultrasonic extraction time, ultrasonic extraction temperature. The optimum ultrasonic extraction conditions of Polysaccharide from Sedum Aizoom L. ： Ultrasonic extraction temperature is 50℃, solid-liquid ratiois 1 ： 50, ultrasonic extraction time is 40min, extraction times is 3, under this extraction condition the highest crude polysaccharide extraction yield was 7.39%. |
