| Abstract: | Objective]The research aimed to optimize the extraction technology of polysaccharide from Dendrobium tosaense Makino.Method]Using the content of polysaccharide from Dendrobium tosaense Makino as an evaluation standard,choosing extraction temperature,dosage of water,extraction time and extraction times as the observation factors,the influencing factors of the extraction technology of polysaccharide from Dendrobium tosaense Makino were studied by using L9(34) orthogonal test.Result]The optimum extraction technology of polysaccharide from Dendrobium tosaense Makino was as follows:extracting for three times,using ten times amount of water,with every extraction time of 2 h at 90 ℃.Conclusion]Among experimental design factors,the temperature and extraction time had a significant role in the extraction. |
