Macroporous resin was used to enrich flavonoids in the ethyl acetate extract of Artemisia Selengensis Turcz. Based on a single factor experiment, the enrichment process was optimized using the response surface method. The optimal parameters of the enrichment process were a sample concentration of 0.3 mg/mL, a loading rate of 1 mL/min, an elution flow rate of 2 mL/min, and a total flavonoid content of 155.38 ± 0.97 mg/g. The flavonoids enriched by AB‐8 macroporous resin demonstrated significant scavenging activities against DPPH, ABTS+, and hydroxyl free radicals, and also exhibited certain inhibitory effects on α‐amylase and α‐glucosidase. Among them, the scavenging ability of the flavonoids enriched by AB‐8 macroporous resin on hydroxyl free radical (IC50 = 30.31 ± 1.92 μg/mL) was the closest to Vc, and the inhibitory effect on α‐glucosidase (IC50 = 16.19 ± 1.35 μg/mL) was the best. These findings confirmed the potential of Artemisia Selengensis Turcz. is a natural antioxidant and hypoglycemic drug.
