This study investigated the effect of insoluble dietary fibers extracted from Salicornia herbacea L. (S. herbacea) on the improvement of intestinal function in rats. Sprague-Dawley rats were fed on diet containing 5% and 10% S. herbacea dietary fiber (SHDF) for four weeks. Rats receiving the SHDF diet showed a significant decrease in their triglyceride levels and an increase in HDL-cholesterol levels. In addition, compared with the control group, the SHDF group showed a significant increase in the total quantity of the feces and its moisture content. The intestinal transit time of the feces was also shorter in this group. The pH of the feces decreased in all the other experimental groups. Particularly, the bile acid content of the feces and the thicknesses of the mucus layers showed significant recovery on SHDF intake. These results suggest that dietary fiber isolated from S. herbacea has a marked effect on the improvement of bowel function in rats with loperamide (2 mg/kg)-induced constipation.
