Title: Several extraction processes of polysaccharide from Morus aLba L. leaves
Abstract: Four different extraction procedures of polysaccharide from leaves of Morus aLba L.were studied.The results showed that: (1) The optimum condition of extracting with water was: solid-liquid ratio 1∶40,extraction time 1 h,temperature 80 ℃.And the yield of polysaccharide was 11.50%.(2) The optimum conditions of extracting with ultrasonic assistance were: the ultrasonic power was 300 W and ultrasonic time was 10 min. The yield of polysaccharide was 12.25%.(3) The optimum extracting enzyme was cellulose,the dosage was 1.5%,cellulase treatment time 2 h and treatment temperature 50 ℃.The yield of polysaccharide using enzymatic assistant extraction was 12.49%.(4) The appropriate microwave treatment time was 8 min and the yield of polysaccharide using microwave assistant extraction was 11.68%.(5) The yield of polysaccharide was: enzymatic assistant extraction ultrasound assistant extraction microwave assistant extra-ction water extraction.Considering cost,work efficiency,etc.,ultrasonic assistant extraction was showed to be the most promising extraction method for polysaccharide from leaves of Morus aLba L.
