摘要: 采用单因素实验和正交试验,优化了鼠源α-葡萄糖苷酶抑制剂体外微量筛选模型,并应用该模型研究泽泻正丁醇萃取部分(AOB)在体外对小鼠α-葡萄糖苷酶的抑制活性。结果显示,AOB体外具有较强的小鼠小肠α-葡萄糖苷酶抑制活性,IC50为126 μg/mL。灌胃10 d后,AOB能有效地抑制小鼠体内α-葡萄糖苷酶活性,其活性明显低于生理盐水组。AOB是潜在的高效α-葡萄糖苷酶抑制剂。

Abstract: Slight modifications of microplate-based screening model were carried out with single factor and orthogonal experiments.The inhibitory effect of n-butanol fraction of Alisma orientailis (AOB) on mice intestinal α-glucosidase was assayed by this model.The results showed that AOB significantly inhibited mice intestinal α-glucosidase activity with a dose dependent manner with IC50 value of 126 μg/mL in vitro and suppressed intestinal α-glucosidase activities in normal mice compared with control group after orally administered for 10 days.AOB has the potential to inhibit activities of mice α-glucosidase.

Key words: Alisma orientailis, n-butanol fraction, &alpha, -glucosidase, inhibition, screening model
