Resumen La investigacion tuvo como objetivo evaluar el efecto ansiolitico in vivo del extracto etanolico de Passiflora salpoense S. Leiva & Tantalean (Passifloraceae) en “ratones albinos” Balb/c. Para ello, se trabajo con 20 ratones Balb/c que aleatoriamente fueron distribuidos en 4 grupos administrandoles por via oral (VO) de la siguiente forma: G1: grupo blanco 0,2 ml de solucion salina, G2: grupo diazepam 1 mg/kg, G3: grupo 50 mg/kg de extracto etanolico de P. salpoense y G4: grupo 100 mg/kg de extracto etanolico de P. salpoense . Luego, los ratones fueron inducidos a ansiedad usando el marble burying test o prueba de enterramiento de canicas. Los resultados demostraron que los grupos G3 y G4 disminuyeron de manera significativa el numero de esferas enterradas con una media 9,60 ± 1,82 y 4,20 ± 1,30, respectivamente, a comparacion del grupo control blanco (G1) cuya media fue de 17,20 ± 3,03. Asimismo, los grupos G3 y G4 presentaron una respuesta similar al grupo G2 cuya media fue de 3 ± 0,71. Por lo tanto, se concluyo que las dosis 50 mg/kg y 100 mg/kg del extracto etanolico de P. salpoense disminuyen los niveles de ansiedad de forma significativa (p < 0.05). Palabras clave: Passiflora salpoense , extracto etanolico, ansiedad, marble burying test. Abstract This investigation had as objective to evaluate in vivo the anxiolytic effect of the ethanolic extract of Passiflora salpoense (Passifloraceae) in “albino mice” Balb/c. For this, we worked with 20 Balb/c mice that were randomly distributed in 4 groups for administering them orally in the following way: G1: control group 0.2 ml saline solution, G2: diazepam group 1 mg/kg, G3: group 50 mg/kg of ethanolic extract of P. salpoense , and G4: group 100 mg/kg of ethanolic extract of P. salpoense . Then, the mice were induced to anxiety using the marble burying test. The results showed that the G3 and G4 groups significantly decreased the number of buried spheres with a mean of 9.60 ± 1.82 and 4.20 ± 1.30 respectively, compared to the control group (G1) whose mean was 17.20 ± 3.03. Likewise, the G3 and G4 groups presented a response similar to the G2 group whose mean was 3 ± 0.71. For this reason, it was concluded that the doses of 50 mg/kg and 100 mg/kg of the ethanolic extract of Passiflora salpoense significantly reduce anxiety levels (p < 0.05).
