| Abstract: | The methods of extraction of polysaccharide from Sauropus androgynus（z） Meer were studied,and determination of the polysaccharide was conducted with the phenol-sulfuric acid method.The results showed that ultrasonic-assisted extraction of the polysaccharide in Sauropus androgynus（z） Meer was most efficient.The content of polysaccharide in Sauropus androgynus（z） Meer was about 0.362%.The method was simple,rapid,and accurate. |
