| Abstract: | Objective] To study the best extraction conditions of polysaccharide from corn stalk,so as to provide basis for the further development and utilization of corn stalk resources.Method] The best conditions for the hot water extraction of polysaccharide from corn stalk were determined by orthogonal experiment and single factor test.Result] The influential degree of each factor on the extraction of polysaccharide decreased in the order of extraction time > extraction temperature > material-water ratio.The best extraction conditions were 80 ℃ of temperature,3 h of time and 1∶30(g/ml) of material-water ratio.Conclusion] The hot water extraction method is good for the polysaccharide extraction from corn stalk,and anthrone-sulfuric acid method is practical for determining the extraction rate of polysaccharide,the results are stable. |
