Abstract: To simplify the extraction process of cili polysaccharide so that energy and time can be saved to achieve convenience,water extraction of polysaccharides from roxburgh rose is studied in this paper.Effects of extraction temperature,time,solid-liquid ratio and ethanol concentration are also investigated.Orthogonal test optimization of process and anthrone sulfurie acid method was used for the determination of polysaccharide content.The results indicated that the best technological conditions for extraction is 75 ℃,1 hours,1∶40 solid-liquid ratio,and 0% ethanol concentration.Under these conditions,the yield of polysaccharide from Roxburgh Rose was 4.7%.

Key words: polysaccharide from Roxburgh Rose, orthogonal experiment, extraction process
