Comparative Orthogonal Design and Box-Behnken Design Optimization of Extraction Technology of Empetrum Nigrum L.for Polysaccharide
Objective:To optimize extraction rate technology of polysaccharide.Methods:The polysaccharide extracting rate was the investigation index,through the method of orthogonal design and Box-Behnken design optimization of Empetrum nigrum polysaccharide extraction process research,and then the experimetal results of the two methods were analyzed.Results:Box-Behnken design method showed higher polysaceharide digestion rate than the orthogonal design.Conclusion:The optimum extraction of polysaccharide from Empetrum nigrum L.was smashed herbs to pass through 100-mesh scream,add 15 timesparts of water,voltage 1.75 h under 155 V two times.
