    Abstract:Objective:Different extraction methods (reflux, microwave, supersonic wave, reflux combined enzyme) were used for the extraction of polysaccharide from Panax quinquefolium L. and the best technological parameters were selected.Methods:According to the results of the comparative experiments, it was found that reflux extraction combined enzyme was the most effective method in this case. By making the single factor and orthogonal experiments, the optimum technological parameters for reflux extraction combined enzyme were obtained.Results:The enzymatic reaction temperature of 50℃ for 1.5 h, the ration of material to solvent of 1∶12, the enzyme amount of 20 μl/g, the extraction times of 2 at 100 ℃.Conclusion:The enzyme assisted-extraction was useful in polysaccharide extraction of Panax Quinquefolium.
