Objective: To optimize the extraction process of polysaccharide from Kuli radix distillate by pectinase. Methods: Pectinase was used to extract polysaccharide from Kuli radix distillate under suitable water bath temperature. The optimal combination of polysaccharides from Kuli radix distillate was selected by single factor test and orthogonal test, and the stability, precision and repeatability test were carried out to verify the accuracy of the experimental results. Results: The optimal extraction conditions of polysaccharides from Kuli radix distillate were as follows: the ratio of material to liquid was 1∶25, the time of enzymatic hydrolysis was 105 min, the amount of pectinase was 1.0%, and the temperature of enzymatic hydrolysis was 30 ℃. Under the optimal extraction conditions, the content of polysaccharides in Kuli radix distillate was 59.28±0.01 mg/g. Conclusion: Polysaccharide from Kuli radix distillate can be effectively extracted by enzymatic hydrolysis. The best extraction conditions were determined by single factor and orthogonal test, which provided a theoretical reference for the follow-up study of Kuli radix distillate.
