| Abstract: | OBJECTIVE To study the extraction process of polysaccharide from Caulis Dendrobii.METHOD The optimum extraction process was selected with the orthogonal design.The content of polysaccharide was determined by UV-spectrophotometry.RESULTS After breaking,the times of extracting and the amount of water had marked influence on the extraction of polysaccharide from Caulis Dendrobii.CONCLUSION The optimum extraction process of polysaccharide from Caulis Dendrobii was as following:grind Caulis Dendrobii to rough grains,adding 20 times water,extracting 4 times and 8 hours each time. |
