Abstract: Objective To establishing the best extraction technology of polysaccharide in Bletilla striata and researching its physical and chemical properties. Methods Water extraction and buck formulation, cellulose enzyme hydrolysis and ultrasonic extraction were used, and the spectrophotometry was used to determine the content of polysaccharide, the receiving rate of polysaccharide in the highest method as the foundation, the contents of polysaccharide as the target to process optimization. The physical and chemical characteristics of polysaccharide were studied according to the Ch.P (2010). Results The ultrasonic extraction method was the best extraction technologywith the condition that: the ratio of material and liquid was 1:20, temperature was 80℃, in 10 min.The extraction rate was 49.90%. Five physical and chemical properties were calculated. Conclusion The extraction rate of ultrasonic method for polysaccharide in Bletilla striata was high than other methods, and suitable for mass productionwhich could provide the references for modern application of polysaccharide in Bletilla striata.
