| Abstract: | In order to obtain optimization of ultrasonic extraction of polysaccharides from equisetum,the effect of the solid-liquid ratio,temperature,ultrasonic power and ultrasonic action time on extraction of the polysaccharide by single factor experiment and orthogonal experiment in distilled water were investigated.The optimal ultrasonic extraction conditions were as folllows:solid-liquid ratio(g/mL)1/20,temperature 70℃,ultrasonic power 100 w and ultrasonic action time 50 min.Under this conditions,the average rate of extraction of polysaccharide was 12.33%,RSD was 0.16℅.The ultrasonic extraction of polysaccharides from equisetum was simple,quickly and highly efficient. |
