摘要: 研究灰兜巴醇提石油醚萃取、醇提乙酸乙酯萃取、醇提正丁醇萃取、醇提萃取剩余部分和水提部分对于α-葡萄糖苷酶活性的抑制作用,并通过高效液相色谱检测在药物与酶反应过程中振荡对于α-葡萄糖苷酶抑制率的影响。结果显示,灰兜巴各提取部分均表现出良好的α-葡萄糖苷酶抑制活性,为一种良好的α-葡萄糖苷酶抑制剂,且振荡对其抑制率的影响较大,在反应过程中应使酶与药物充分结合。

Abstract: In this study,the α-glucosidase inhibitory activities of petroleum ether fraction of ethanol extract,ethyl acetate fraction of ethanol extract,n-butyl alcohol fraction of ethanol extract,remaining fraction of ethanol extract and aqueous extract of Huidouba were investigated.The influence of shaking during drug enzyme reaction process on the inhibition rate of α-glucosidase was examined by HPLC.The data suggested that Huidouba extracts showed obvious inhibitory effort on α-glucosidase.In addition,during its reaction with α-glucosidase,shaking showed relative large influence on the inhibition rate of α-glucosidase.

Key words: Huidouba, &alpha, -glucosidase, inhibitory activity, HPLC
