研究了白茅根多糖的抗氧化活性和对α-葡萄糖苷酶的抑制活性，以总还原能力、ABTS自由基清除率、羟基自由基清除率3项指标来评价白茅根多糖的抗氧化活性，并与VC进行比较，采用体外α-葡萄糖苷酶抑制模型，测定白茅根多糖对α-葡萄糖苷酶的抑制作用。结果表明，白茅根多糖的还原能力低于VC，对ABTS自由基有较好的清除作用，IC50为0.0298 mg/mL，对羟基自由基有清除作用，IC50为1.1 mg/mL。白茅根多糖对α-葡萄糖苷酶的抑制作用较低。

To study the antioxidant activity and α-glucosidase inhibitory activity of polysaccharide from Imperata Cylindrica. The antioxidant activities were examined from the aspects of reducing power ,scavenging rate of ABTS+· and hydroxyl free radicals respectively,and compared with VC. The α-glucosidase inhibitory activities were assayed in external model. The Results showed that the reducing power of Imperata Cylindrica polysaccharide was weaker than VC. The polysaccharide had a good effect on ABTS+·and·OH scavenging, the IC50 value was 0.029 8 mg/mL, 1.1 mg/mL respectively.
