Effect of oil palm phenolics on gastrointestinal transit, contractility and motility in the rat

The effects of a novel water soluble polyphenolics preparation (oil palm phenolics; OPP) on whole gastrointestinal transit, ex vivo proximal and distal colonic contractility and intact expulsion time in the distal colon were examined. Nine weeks of dietary supplementation with OPP at 50 mg gallic acid equivalents (GAE)/rat per day had no effect on gastric emptying compared to the control (AIN-93M), but 30% substituted high amylose maize starch...
