METHODS ：Extraction temperature ，extraction time ，ratio of material to liquid and extraction times were investigated by single factor test and RSM using the yield of M. alba polysaccharides as index to optimize the extraction technology.RESULTS ：The optimal condition obtained from RSM was as follow ：extraction temperature 100 ℃，the ratio of material to water 1∶20，extraction time 2.5 h ，and extracting for 2 times. The yield of polysaccharides was 6.15％，which was in line with predicted value basically. CONCLUSION ：The model could well predict the yield of M. alba polysaccharides ，and RSM is feasible to optimize the extraction technology of M. alba polysaccharides.
