| Abstract: | Microwave-assisted extraction was applied for polysaccharide extraction from Morus alba L.. Factors and levels were optimized by single factor test. Box-Behnken design was used to 3-factors and 3-levels test. The optimal process conditions were obtained by regression analysis of response surface methodology. The results showed that the optimal polysaccharide extraction process conditions were obtained by microwave-assisted extraction as follows： extraction temperature was 88%, extraction time was 11 minutes and liquid/solid ratio was 18：1, the maximum of polysaccharide content was 15.20 mg/g. Polysaccharide content of microwave-assisted extraction was higher 2.18 fold （extraction time： 10min） and 0.23 fold （extraction time： 60 min） than that of traditional extraction, respectively. |
