Ultrasonic extraction for polysaccharides from Epimedium sagittatum(Sieb.Et Zucc.)Maxim
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 from E.sagittatum by hot water extraction method were as follows:material/liquid ratio 1:80,temperature 80℃,time 60min,pH 8.0.The optimum conditions for extracting polysaccharides from E.sagittatum by ultrasonic-assisted extraction method were as follows:material/liquid ratio 1∶60,ultrasonic operative power 100W,pH 7.0,time of 10min.The ultrasonic extracting method was better than the hot water extracting method.
