摘要：该研究采用超声提取食叶草多酚，并研究其对α-葡萄糖苷酶的抑制活性。在单因素试验的基础上，采用响应面试验优化得到超声提取食叶草多酚的最优条件为乙醇体积分数60%、超声功率250W、提取时间31min。在此条件下多酚得率为（12.55±0.26）%。食叶草多酚具有较高的α-葡萄糖苷酶抑制活性，IC50为1.73mg/mL。研究结果可为食叶草多酚的提取及其功能开发提供参考。

Abstract：This study extracted polyphenols from Rumex Hanus using ultrasound and studied their effects on α-glucosidase inhibitory activity. Based on the single factor test， the ultrasound-assisted extraction of polyphenols from Rumex Hanus were optimized by response surface method. The optimum conditions for ultrasound-assisted extraction were ethanol volume fraction content 60%， ultrasonic power 250 W， extraction time 31 min. Under these conditions， the yield of polyphenols was（12.55 ± 0.26）% . Polyphenols from Rumex Hanus have higher α-glucosidase inhibitory activity， the IC50 was 1.73 mg/mL. The results can provide reference for the extraction of polyphenols and the development of its function.
