摘要：

The flavonoids in mulberry leaves have good antioxidant activities. In this study, ultrasound-assisted extraction was used to obtain the crude flavonoids, and the macroporous resin adsorption technology was further employed to purify the flavonoids. The nonpolar resin labeled as H-103 was selected from eight kinds of macroporous resins as the adsorbent. Static and dynamic adsorption-desorption were tested to optimize the operation parameters. The experimental results show that the purity of the total flavonoids can be 36.3%, with a recovery of 83.4% under the optimum conditions. The flavonoids of rutin and isoquercitrin in the extract were detected by high-performance liquid chromatography, and their recoveries were above 80%. The devised method of isolation of the flavonoids from mulberry leaves may be used to develop a new process for medicinal purpose.
