The purpose of this study was to investigate the effect of the water-soluble polysaccharide-rich sage weed (Salvia plebeia) extracts on intestinal function. The results showed that the extract is rich in water-soluble polysaccharides (60.5/100 g extract), which are mainly composed of pectic polysaccharides and hemicellulose. The inclusion of sage weed extract in the control diet at a level of 0.5/100 g diet resulted in significantly (P < 0.05) improved effects on intestinal and faecal parameters of the hamsters, such as shortened gastrointestinal transit time, reduced caecal ammonia, decreased daily faecal ammonia output, increased short-chain fatty acid concentrations in caecal content, and lowered activities of ¦Â-d-glucuronidase, ¦Â-d-glucosidase, mucinase, and urease. These findings suggest that an adequate intake of sage weed extracts (0.5/100 g diet) may play a role in the maintenance of intestinal health by reducing the exposure of intestinal mucosa to toxic materials and other harmful compounds.
