Beneficial Regulatory Effects of Sesamin on Intestinal Flora of Mice

The effects of sesamin on intestinal microflora of mice with normal diet were studied by in vitro animal feces anaerobic culture system.The results showed that treatment with sesamin could significantly change the intestinal flora structure of mice,increasing the abundance of probiotics Lactobacillus and Bifidobacterium and inhibiting the growth of harmful bacteria Enterococcus.High-throughput sequencing analysis showed that sesamin could affect the structure and composition of fecal microflora of mice,and the abundance of probiotics such as Bacillus and Bifidobacterium increased.Sesamin also could increase the expression of tight contiguous protein Occludin and Claudin-1 in colonic tissue of mice,which was benefit to the adhesion of probiotics.In conclusion,sesamin intervention could improve the composition and abundance of intestinal microorganisms in mice with normal diet,which had a beneficial regulatory effect on the intestinal health.
