Abstract: Microwave sample preparation instrument was used to extract polysaccharides from bletilla striata.Extraction parameters,time,power and ratio of liquid to material were optimized through response surface methodology.The results showed that the theoretical analysis is accurate and credible.The optimal conditions of extracting polysaccharides from bletilla striata are as follows: ratio of liquid to material 75mL/g,time 15min,and power 100W.Under these conditions,95% polysaccharides can be extracted at the first time.

Key words: microwave, response surface methodology, polysaccharides, bletilla striata
