摘要
目的比较桃胶多糖、抗性淀粉和低聚果糖对正常大鼠肠道益生菌生长的影响。方法将正常大鼠随机分为正常对照组、桃胶多糖组、抗性淀粉组和低聚果糖组,除正常对照组外,其余大鼠分别予桃胶多糖、抗性淀粉、低聚果糖每日5g/kg连续灌胃,20d后检测大鼠体质量和肠道益生菌的生长变化。结果与正常对照组比较,桃胶多糖组、抗性淀粉组和低聚果糖组大鼠体质量无明显变化(P>0.05);桃胶多糖、抗性淀粉和低聚果糖均能显著促进双歧杆菌、乳杆菌的增长(P<0.01),以低聚果糖组效果显著为优(P<0.01)。结论桃胶多糖、抗性淀粉、低聚果糖均能明显促进双歧杆菌、乳杆菌的增长。
Objective To compare the effects of peach gum polysaccharide, resistant starch, and fructooli- gosaccharide on the growth of intestinal probiotics in normal rats. Methods Normal rats were randomly divided into normal control group, peach gum polysaccharide group, resistant starch group, and fructooli- gosaccharide group. Each rat in the peach gum polysaccharide group, resistant starch group, and fructooli- gosaccharide group received intragastric administration of peach gum polysaccharide, resistant starch, or fructooligosaccharide （5 g/kg daily） for 20 days. Their body weights and numbers of intestinal probiotics were measured before and after treatment. Results Compared with the normal control group, the peach gum polysaccharide group, resistant starch group, and fructooligosaccharide group showed no significant changes in the body weights, but the three groups, particularly fructooligosaccharide group, had signifi- cantly increased Bifidobacterium and Lactobacillus in the intestinal tract （P〈0.01）. Conclusion Peach gum polysaceharide, resistant starch, and fructooligosaccharide can markedly promote the growth of Bifidobacterium and Lactobacillus in the intestinal tract.
