Abstract:
Taking Dryopteris cochleata as material,the effect of extraction temperature,solid-liquid ratio,extraction time and the ethanol concentration on polysaccharide yield were studied by single factor test,and the extraction technology was optimized by orthogonal experiment.The results showed that the best extraction technology of polysaccharide from Dryopteris cochleata was the extraction time 2.5 h,the solid-liquidratio 1∶40 g/mL,the ethanol concentration 80%and extraction temperature 80℃.Under these conditions,the extraction rate of polysaccharide was 2.60%.The optimized extraction process was reliable,and the extraction efficiency of polysaccharide was higher than normal with good quality.
