低聚甘露糖

研究魔芋低聚甘露糖对小鼠的通便作用。

To study the purgation effect of Mannose oligomer in Amorphophallus konjac .

本文以褐藻胶和κ-卡拉胶为原料通过酸水解分别获得了低聚的甘露糖醛酸、古罗糖醛酸和低聚κ-卡拉胶，并采用HPGPC法测定了这3种低聚糖的重均分子量。

Low molecular weight mannuronic acid , guluronic acid and κ carrageenan were prepared from algin and carrageenan by the acid hydrolysis method , and their weight average molecular weights and the distribution widths of molecular weight were determined by high performance gel permeation chromatography ( HPGPC ) respectively .

结论：1.大豆低聚糖、低聚木糖、低聚果糖、低聚甘露糖对人胃癌细胞株BGC-823细胞有一定程度的抑制作用，其中大豆低聚糖作用最强。

The inhibition of soybean oligosaccharide , Xylo - oligosaccharides , Fructo-oligosaccharides , Man-oligosaccharides on proliferation of BGC-823 is evident in vitro , and soybean oligosaccharide has the most obvious roles among them . 2 .

在这四种益生元中，大豆低聚糖的抑制效果最强，低聚木糖次之，低聚果糖，低聚甘露糖的抑制效果较弱。

Among these four prebiotics , soybean oligosaccharide has the most obvious effect , Xylo-oligosaccharides follow it , Fructo-oligosaccharides , Man-oligo - saccharides have fewer roles than them .
