Antidiarrheal Activity of Dialium guineense Willd Fruit Pulp in Wistar Rats

Abstract

Objective. This study is aimed at evaluating the effects of Dialium guineense Willd fruit pulp powder on diarrhea induced by castor oil in Wistar rats. Materials and Methods. Three different tests were carried out. A preventive test by administration of a single dose of 250, 500, 1000, 2000, and 4000 mg/kg before the induction of diarrhea by castor oil. Another preventive test after repeated administration of Dialium guineense at 250, 500, and 1000 mg/kg/day for 8 days, before the induction of diarrhea, was done. The third test was a curative test with a single dose of 250, 500, 1000, and 2000 mg/kg after the induction of diarrhea by castor oil. Results. D. guineense fruit pulp at 1000, 2000, and 4000 mg/kg administered before the induction of diarrhea, has significantly delayed diarrhea; reduced the frequency of defecation, reduced the amount of diarrheal stools, and also reduced the purging index, with a degree of inhibition comparable to that of loperamide. But the water content of the stools of the group treated with D. guineense does not change significantly compared to the controls. D. guineense has reduced significantly from 500 mg/kg the diarrhea induced by castor oil after 8 days of treatment. It appears that the doses of 250 and 500 mg/kg, which were not effective with the single-dose preventive test, significantly delayed diarrhea; reduces the frequency of diarrheal stools and also reduces the purging index. D. guineense administered, after the induction of diarrhea, by castor oil has significantly reduced the diarrhea from 250 mg/kg. Conclusion. The fruit pulp of D. guineense has showed antidiarrheal activities in Wistar rats by reducing the frequency of defecation, the amount of diarrheal fecal matter emitted as well as the water content. It also delayed the onset of diarrhea and significantly reduced the purging index like loperamide.

Chemical Identification, In vitro Antidiarrheal Potential, and Toxicological Study of the Leaves of Combretum grandiflorum G. Don (Combretaceae), a Beninese Medicinal Plant

“…The antifungal activity of the active extracts was determined by the solid medium diffusion method according to the method of Alsubhi et al [26]. For the antifungal test itself, Potatose Dextrose Agar (PDA) agar plates were inoculated with the fungal suspension prepared for each type of extract.…”
