| Abstract: | Objective] The reference basis for the establishment of efficient and economic extraction of the polysaccharides was provided,which would lay the foundation for the further development of red mushroom.Method] The extraction process of polysaccharide from red mushroom sporophore was studied.Based on the experiment in the ratio of material to water,the extraction temperature and extraction time,the extraction process was optimized with L9(34) orthogonal design.Results] The experimental result indicated that the distilled water was the best solvent.The orthogonal testing results showed that the factor influencing the extraction rate was followed by the extraction temperature,the ratio of material to water,the extraction time and the number of extraction.The optimum parameter was:the ratio of material to water,1∶25;the extraction temperature,100 ℃,the extraction time,240 min and the number of extraction,1 time.Conclusion] The better results of the polysaccharide-extracted from red mushroom could be produced under the optimal extraction process. |
