摘要: 研究徐薯18和大地1号两个品种红薯茎叶多糖和黄酮提取物对四氧嘧啶治糖尿病小鼠血糖水平和α-葡萄糖苷酶活性的影响。结果表明,红薯茎叶多糖和黄酮提取物对四氧嘧啶致糖尿病小鼠具有显著的降血糖作用。红薯茎叶多糖和黄酮提取物具有体外抑制α-葡萄糖苷酶活性的作用,但均弱于阿卡波糖。黄酮提取物对α-葡萄糖苷酶的抑制作用强于多糖提取物,且呈现明显的量效关系。徐薯18红薯茎叶黄酮提取物和多糖提取物的降血糖作用和对α-葡萄糖苷酶的抑制作用均好于大地1号。

Abstract: The Hypoglycemic effects and inhibition on α-glucosidase of polysaccharides and flavonoids extracts from two varieties of sweet potato stem and leaf are studied in this paper. The results showed that the polysaccharides and flavonoids extracts from sweet potato stem and leaf have significantly hypoglycemic effect on experimental diabetic mice. Also, they can inhibit α-glucosidase, but they are all weaker than acarbose. The inhibition ratio of flavonoids extracts obviously presents dose-effect relationship, while the polysaccharides extracts is opposite. The inhibition and hypoglycemic effect of polysaccharides and flavonoids extracts from Xushu 18 is better compared with Dadi I’ respectively.

Key words: sweet potato stem and leaf; polysaccharides extracts; flavonoids extracts; hypoglycemic effects; &alpha, -glucosidase;
