摘要:

研究西青果提取物对小肠α - 葡萄糖苷酶的抑制作用。西青果提取物在体外和小肠模型人类结肠Caco-2 细胞中,显示很强的麦芽糖酶抑制活性,而对蔗糖酶的抑制作用不显著。在体内实验中,西青果提取物能降低SD雄性大鼠进食麦芽糖30min 后的血糖,而对进食蔗糖后的血糖浓度没有影响。实验结果表明西青果提取物可以预防Ⅱ型糖尿病。

Abstract:

In order to evaluate the inhibitory effect of Terminalia chebula Retz fruit extract (TCFE) on α-glucosidase, Caco- 2 cells were used to assay the inhibitory activity of TCFE in vitro and in small intestinal model. Results indicated that TCFE exhibited a strong inhibitory effect on maltase, while no obvious inhibitory activity on sucrase in vitro was observed. In addition, TCFE also obviously reduced 30 min postadministration blood glucose level of SD maltose-loaded male rats. On the other hand, this extract had no effect on the postprandial blood glucose level in normal SD rats administrated sucrose. These results suggest that TCFE has a preventive effect against Type II diabetes.

Key words: Terminalia chebula Retz, &alpha, -glucosidase inhibitor, blood glucose level, diabetes
