Zusammenfassung:The invention provides a method for preparing a hedysarum polybotrys extract by adopting a coupling technology. The method comprises the following steps of: carrying out heating reflux extracting on hedysarum polybotrys; adding commercially available pectinase in a water extracting solution with the temperature of 15-60 DEG C; carrying out enzymolysis and sedimentation; removing insoluble impurities to obtain an enzymolysis extracting solution; carrying out ultra-filtering on the enzymolysis extracting solution; or, directly carrying out ultra-filtering on the water extracting solution; carrying out ultra-filtering on diluted trapped fluid for 2-4 times under the same condition, i.e. diluting the trapped fluid subjected to ultra-filtering each time and then carrying out ultra-filtering on the diluted trapped fluid subjected to ultra-filtering, ensuring that the volume of the trapped fluid subjected to ultra-filtering for the last time does not exceed 20 percent of the volume of the enzymolysis extracting solu
