  The present invention provides an α-glucosidase inhibitor containing a novel epigallocatechin gallate trimer and an epigallocatechin gallate polymer. Decomposition of starch derived from a meal and sugar derived from a polysaccharide can be suppressed by α-glucosidase inhibitory action, thus suppressing absorption. A food and drink excellent in α-glucosidase inhibitory action for suppressing sugar absorption and further for preventing diabetes for a long time can be provided by adding the α-glucosidase inhibitor to a food and drink.

  本发明提供了一种含有新型表没食子酸儿茶素三聚体和表没食子酸儿茶素聚合物的α-葡萄糖苷酶抑制剂。通过α-葡萄糖苷酶抑制作用，可以抑制来源于餐食的淀粉和多糖分解产生的糖的吸收，从而达到抑制吸收的目的。将α-葡萄糖苷酶抑制剂添加到食品和饮料中，可以提供具有优异α-葡萄糖苷酶抑制作用的食品和饮料，进而长期预防糖尿病的发生。
