ABSTRACT

Objetivo: Determinar el efecto del extracto etanólico de la hojas de Mayteus, macrocarpa, “chuchuhuasi” sobre la motilidad intestinal en ratón. Material y Métodos: Se utilizó 50 ratones albinos machos, con pesos medios de 25g, se empleó el método de Arbos y otros, se administró carbón activado al 5% vía oral, dosis de 0.1ml/10g, como marcador intestinal. Los grupos experimentales fueron: Control (agua destilada 0.1ml/10g de peso corporal), Sulfato de Antropina 1mg/kg, Neostigmina 1mg/kg, extractoetanólico de las hojas de M. macrocarpa 1,000mg/kg y extracto etanólicode la hojas de M. macrocarpa 200mg /kg. Para la validaci¢n estadística se usó la prueba de Shapiro-Wilk, ANOVA, Tukey y Newman-keuls. Resultados: el porcentaje de recorido intestinal de carbón activado fue de 43.28%, 33.03%, 74.37%, 67.52% y 63.09% respectivamente. El test de ANOVA de dos colas reveló una p=0.0001. el test de Tukey y Newman-Keuls, indicaron un valor p<0.05 versus el control y Atropina, el test de Shapiro-Wilk presento un valor p<0.05. Conclusiones: El extracto etanólico de la hojas de m. macrocarpa, presenta una actividad estimulante de la motilidad intestinal del roedor.


Objective: To determine the activity of the etanolic extract from the leaves of Maytenus macrocarpa “chuchuhuasi” in the gastrointestinal motility in mice. Material and Methods: We used male albino mice with an average weight of 25g, Arbos and others method was applied. Activated charcoal was administered at 5% at dose of 0.1ml/10g, as an intestinal marker. The experimental groups included 0.1 ml/10g of distilled water, 1 mg/kg of atropine, 1 mg/kg of neostigmine, leave extract of M. macrocarpa 1000 mg/kg and leave extract of M. macrocarpa 2000 mg/kg. The statistical validation was based on Shapiro-Wilk, ANOVA, Tukey and Newman-kleuls test. Results: the intestinal charcoal run percentage was 43.28%, 33.03%, 74.37%, 67.52% and 63.09% respectively. The ANOVA test result in p=0.0001. The Tukey and New-Keuls test indicated p<0.05 versus the control group and atropine, for the last the Shapiro-Wilk test result in p<0.05. Conclusions: The etanolic extract from the leaves of M. macrocarpa “chuchuhuasi” induced stimulating activity on gastrointestinal motility in mice.
