Abstract: The effect of cold water crude extract of stem-bark of Erythrophleum suaveolens on the activity of an isolated guinea-pig Ileum was studied. Reference drugs (Acetylcholine; Histamine; Barium Chloride; Atropine; Promethazine; and Papaverine) were used both in the presence and absence of E. suaveolens extract. Preliminary pharmacological investigation of the extract revealed inhibitory effects. Thus; investigations carried out on the isolated ileum tissue of the guinea-pig (Cavia porcellus) by running a dose-response relationship of the agonist test drugs (Acetylcholine; Histamine; and Barium Chloride) in the presence of the cold water crude extract of stem-bark of Erythrophleum suaveolens ascertained antagonist nature of the extract with a right shift. However; the degree of shift in presence of Barium Chloride is less than that with Histamine and Acetylcholine respectively.
