| Sumario: | The present study was designed to investigate antioxidant, antidiarrhoeal and cytotoxic potential of hydromethanolic extract of the fruit rind of Punica granatum Linn. A dose dependent scavenging of DPPH radical and NO was observed with significant total antioxidant capacity with the plant extract in 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, total antioxidant capacity and nitric oxide (NO) scavenging assays. The extract was also studied for antidiarrhoeal property using castor oil and MgSO<sub>4</sub> -induced diarrhoeal model, and charcoal induced gastrointestinal motility test in mice. At the doses of 200 and 400 mg/kg body weight, the extract reduced the frequency and severity of diarrhoea in test animals throughout the study period. At the same doses, the extracts significantly (p < 0.001) delayed the intestinal transit of charcoal meal in test animals as compared to the control. The extract also displayed strong cytotoxic potential with LC<sub>50</sub> value of 10 μg/ml in brine shrimp lethality bioassay. |
