The optimal process of extracting polysaccharides from Epimedium sagittatum(Sieb.Et Zucc.)Maxim was studied by single factor experiment and orthogonal experiment in this paper.The results show that:The optimum conditions for extracting polysaccharides fromEpimedium sagittatumby hot water extraction method were as follows:material/liquid ratio of 1∶80,temperature of 80℃,time of 60 minutes,pH of 8.0.The optimum conditions for extracting polysaccharides fromEpimedium sagittatum by microwave assisted extraction...
