Inhibitory effect of Aronia melanocarpa fruit juice on intestinal transit rate in rats

Aronia melanocarpa fruit juice (AMFJ) is rich in phenolic substances, mainly flavonoids and tannins. The influence of AMFJ (5 and 10 ml kg−1) on the gastrointestinal propulsion of charcoal meal in rats was investigated. AMFJ dose-dependently reduced the rate of intestinal transit and the effect was statistically significant at the dose of 10 ml kg−1. This reduction of the intestinal transit rate might be due to the the presence of flavonoids and tannins in the juice
