Abstract:The effect and dosage of asparagus oligosaccharides on enhancing small intestine movement were in－ vestigated. Animal experiment was adopted， and the mice （male， weight 20±2 g） were divided into two trail groups， in which it had 60 mice. The first group engaged in the smallintrtine-propulsive-experiment， the sec－ ond group engaged in the defecation experiment， the trail time was 15 days. Each trail group was divided into the low， middle， and high three dose groups， blank group and model group， the results were analyzed statisti－ cally by SPSS software.The results showed that：small intestinal propulsion rate had significant difference be－ tween the model and the three dose groups （P<0.05）， the fecal quantity of the mice in the middle， high groups was higher than the model group， and it had significant difference （P<0.05）. The asparagus oligosaccharide could enhance the peristalsis of small intestine， shorten the first defecation time and increase the fecal grains and weight， which had a laxative effect.
