| Abstract: | Objective ] To extract the polysaceharide and measure the polysaeeharide content in Radix Codonopsis pilosulae. Method ] The polysaecharide was obtained with the water extraction and alcohol precipitation method, and the polysaecharide content of the extraction was measured with the Phenol-sulfuric acid method. Result ] The polysaecharide content in Radix Codonopsis pilosulae was 30.49% , the rate of recovery was 99.24%, and RSD was 2.32% （ n = 6 ）. Conclution ] Polysaccharide content of Radix Codonopsis pilosulae in Gansu was high, and it has higher value of development and utilization. Ultrasonic extraction was an effective method of polysaccharide extract. |
