Method for evaluating adsorption performance of macroporous resin for purifying desmodium styracifolium extract

The invention provides a method for evaluating the adsorption performance of macroporous adsorption resin for purifying a desmodium styracifolium extract. The method comprises the following steps: providing a loading solution containing the desmodium styracifolium extract; loading macroporous adsorption resin into a column, and pre-treating the obtained resin column; carrying out purification treatment on the loading solution, namely loading the loading solution to the resin column obtained by pretreatment, and collecting effluent; putting the water sample into a resin column, and collecting water eluate; loading an ethanol sample into the resin column, and collecting an alcohol eluent; respectively measuring the schaftoside content in the loading solution, the effluent, the water eluate and the alcohol eluate, and calculating the desorption rate; the adsorption performance of the macroporous adsorption resin is determined based on a desorption rate calculation result, the adsorption performance of the macrop
