Abstract: Object: In order to know the extraction technology of soluble polysaccharides from radix Cynanchum bungei. Methods:single factor test and orthogonal experiment design methods L9(33) were applied to analyze the influence of each factor in solid-liquidratio, temperature and time on the extraction percent of the polysaccharides. Results: Experimental results indicated that tempera-ture and solid-liquid ratio significantly affect the extraction percent of the soluble polysaccharides. Conclusion The optimum solid-liquid ratio is 1:20,temperature is 100℃ and the extraction time is 2h, the extraction degree is 1 time.

Key words: Cynanchum bungei Decne, soluble polysaccharides, extraction technology
