Quercitrin,hyperoside,rutin and afzelin are the dominant flavonoids compounds from Zanthoxylumbungeanum leaves and play major roles on the antioxidant activity.Macroporous adsorption resin(MAR)as a simple,low cost and efficient method was combined with the ultrasound-assisted extraction(UAE)to enrich and purify these four flavonoids from Z.bungeanum leaves efficiently.The optimal conditions for UAE based on Response Surface Methodology(RSM)were determined as ethanol of 60%,leave of 40 meshs,temperature 40℃ and ultrasonic power 400 W with four flavonoids contents of 120.84 mg/g.After the extraction process,five kinds of MARs(D4020,D-101,NKA-9,AB-8 and X-5)were tested through static adsorption/desorption to enrich and purify the crude extracts,and D-101 was selected as the suitable type.
