Dennettia tripetala Combats Oxidative Stress, Protein and Lipid Dyshomeostasis, Inflammation, Hepatic Injury, and Glomerular Blockage in Rats.

Dennettia tripetala, better known as 'pepperfruit', is a medicinal plant consumed in West Africa. D. tripetala possesses strong antioxidant properties and contains uvariopsine, an alkaloid which improves bile secretion and liver function. In the present study, the ethanolic extract of D. tripetala fruits was tested for its ability to alleviate pathophysiological conditions bordering on oxidative stress, including protein and lipid dyshomeostasis, inflammation, and hepatic and glomerular injury. Male albino Wistar rats were administered carbon tetrachloride twice a week for two weeks, and the ethanolic extract of D. tripetala fruits was administered from days 8∼14. The serum, liver, and kidneys of the rats were then subjected to biochemical assays and imaging. The extract restored the activities of liver marker enzymes in serum and the concentrations of lipids and proteins in both circulation and the liver to normal. The extract also restored the activities of antioxidant enzymes in liver and kidneys, and the concentrations of urea and creatinine in the blood. The extract also repaired the altered structures of the liver and kidney. Overall, D. tripetala elicited strong medicinal effects in rats. This study showed that the fruits of D. tripetala contain substances that could be extracted or synthesized for use in drugs for the treatment of liver and kidney disease.
