Abstract

The inhibitory effect of different polyphenolic plant compounds on alpha-amylase activity was investigated in vitro. A kinetic assay was performed using 96-well-plates. Acarbose was used as positive control (IC50: 23.2 microM). Some of the tested compounds, occurring in plants traditionally used in anti-diabetic tea species, showed an inhibition of the enzyme in physiological concentrations, e.g. luteolin, tannic acid, and isochlorogenic acid.

摘要

在体外研究了不同多酚类植物化合物对α-淀粉酶活性的抑制作用。使用96孔板进行动力学测定。阿卡波糖用作阳性对照(IC50:23.2微摩尔)。一些存在于传统用于抗糖尿病茶品种的植物中的受试化合物,在生理浓度下显示出对该酶的抑制作用,例如木犀草素、单宁酸和异绿原酸。
