Abstract

Diarrheal disease is a major health problem in developing countries. It is the second leading cause of death among children under five globally; accounting for about 9 percent of all deaths. This study was aimed at evaluating the antidiarrheal activity of the aqueous leaf extract of Senna surattensis. The antidiarrheal effect of the extract was evaluated using castor oil-induced diarrhea model. Loperamide was used as the standard drug. Thirty (30) Wistar rats were divided into six (6) groups of five (5) rats each. Groups I and II served as the normal and negative controls respectively, group III as standard treatment and groups IV, V and VI as test groups. The extract was administered orally at three different doses of 100 mg/kg, 200 mg/kg and 400 mg/kg to groups IV, V and VI respectively. The extract exhibited a graded dose-dependent inhibition of castor oil-induced diarrhea. The stool inhibition was highly significant at 100 mg/kg (88.1% inhibition) and maximal at 400 mg/kg (100% inhibition). The maximal effect produced by the extract at 400 mg/kg (100% inhibition) is similar to that of the standard drug (5 mg/kg loperamide) which produced 97.6% inhibition. The extract also exhibited a modest dose-dependent reduction on the distance travelled by the charcoal meal. This extract high doses, significantly decrease the volume of the intestinal content when compared to that of the negative control. The results obtained from this study suggests that the aqueous leaf extract of Senna surattensis have significant antidiarrheal effect on animal models and this finding supports the traditional use of this plant extract for treatment and or management of diarrhea.

Abstract

Diarrheal diseases are a major public health problem in developing countries. Anogeissus leiocarpus is used in Africa and particularly in Nigeria for the empirical treatment of diarrhea. The present study was undertaken to evaluate the effects of aqueous stem bark extract of Anogeissus leiocarpus on castor oil-induced diarrhea in rats. Thirty (30) Wistar rats of both sexes were grouped into six groups (the first three of which served as the normal control, negative control and standard treatment respectively, the last three were used as test groups) of five rats per group. Diarrhea was induced by administering 1 ml/rat of castor oil orally. Phytochemical screening of the aqueous stem bark extract of Anogeissus leiocarpus revealed the presence of alkaloids, flavonoids, steroids, tannins, saponins and phenols. Treatment with the extract produced a significant dose-dependent inhibition of diarrhea. The percentage inhibition of diarrhea increased with corresponding increase in dose of the extract and was comparable with the percentage inhibition produced by the standard drug (loperamide). Treatment with this extract also produced a modest dose-dependent reduction on intestinal transit in rats and a statistically significant (p<0.05) dose-dependent reduction in the volume of intestinal content when compared with the negative control group. The results obtained from this study suggests that the aqueous stem bark extract of Anogeissus leiocarpus have significant antidiarrheal effect on animal models and this finding supports the traditional use of the plant extract in the management of diarrhea.
