Keywords:
Diospyros peregrina, Ebenaceae, Diarrhoea, Dysentery, Traditional MedicineAbstract
Diospyros peregrina Gruke. (Ebenaceae) possesses a number of medicinal properties, and is used in Bangladeshi traditionalmedicine. In this study, the methanol extracts of the barks and seeds of this plant have been investigated inthe castor oil induced diarrhoea model in mice. The extracts were also studied for their anti-bacterial properties bydisc diffusion method against a number of pathogenic bacteria responsible for causing diarrhoea and dysentery. Atthe doses of 250 and 500 mg/kg body weight, the extracts delayed the onset of diarrhoea. The extracts also reduced thefrequency and severity of diarrhoea in test animals throughout the study period. At the same doses, the extracts delayedthe intestinal transit of charcoal meal in test animals as compared to the control, and the results were statistically significant. In both cases the seed extract was found to be more potent than the bark extract. The bark extract inhibitedthe growth of Staphylococcus aureus, Shigella dysentery, Escherichia coli and Pseudomonas aeruginosa, whereas theseed extract demonstrated inhibitory activity against S. aureus, S. dysentery and E. coliDownloads
