| Abstract: | Factors affecting the extraction technology of polysaccharide from Aucklandia lappa was studied to build the foundation for its separation and purification.Using the yield of polysaccharide as index,orthogonal experiment was adopted to optimize the water extraction method and alcohol precipitation method.The optimum extraction scheme was as follows,solid to liquid ratio,1∶18(m/V,g∶mL);extraction time,2 h;extraction temperature,80 ℃;crude herbal dose,1 mL/g;volume fraction of alcohol,80%;extracting twice. |
