Objective: Determinate the mechanisms of interaction between the ethanol extract of Jatrohpacurcas L. and metoclopramide on gastrointestinal system. Material and Methods: 30 male albino mice were used, forming 5 groups and received oral medications as follows: Group 1: Jatropha curcas L. 800 mg / kg, and 0.5 mg/Kg of metoclopramide. Group 2: 0.5 mg/mL of metoclopramide. Group 3: 1.5 mg/Kg of atropine. Group 4: 800 mg/Kg of Jatropha curcas L. Group 5 received no medication. All groups receivedoral activated charcoal 0.1 mL/10g as intestinal marker. The Arbos et al method was used to evaluate intestinal motility. The statistical validation of the intestine dynamics was performed using the Kolmogorov Smirnov, 1-tailed ANOVA, Tukey and Newman-Keuls. Results: the percentage of charcoal runs in the 1rst group was 36.46% compared to 65.45%, 3.66 % and 58.87% for the 2nd, 3th and 4th groups, respectively. In the 4th group was 58,87% compared to 20.94% in the 5th group. Conclusion: the antagonism between the ethanol extract of the seeds of J.curcas L. with metoclopramide, which is probably would explain by the interaction between the cholinergic system, adrenergic system, GABAergic system and neuropeptides on the adrenal gland, central nervous system and gastrointestinal system

Keywords : metoclopramide; Jatrophacurcas; gastrointestinal motility.
