摘　　要：研究了葛根、桑叶、山药3种天然产物的提取溶液对α-淀粉酶活性的抑制作用。结果显示除了山药对α-淀粉酶无明显抑制作用,葛根、桑叶对α-淀粉酶均有显著抑制作用,对α-淀粉酶半抑制浓度(IC50)分别为56.72,46.57 mg/mL,抑制效果可分别达到现有α-淀粉酶抑制剂拜糖平的1.12,1.36倍。The α-amylase inhibitory activities of the extracts from Radix Puerariae, Folium Mori and yam was studied. The results showed that, except the extracts of yam the rest of two natural products have obvious effect on inhibiting α-amylase, and the 50% inhibiting concentration （IC50, mg/mL） is 56.72, 46.57 mg/mL, respectively, which is 1.12, 1.36 times stronger than that of acarbose.
