Abstract

The objective of this research work was to determine the in vitro anti-inflammatory activity of ethanolic extract from the bark of Maytenus macrocarpa (Ruiz &Pav.) Briq. "chuchuhuasi" and Justicia spicigera Schltdl "insulin" leaves by the method of stabilization of the red blood cell membrane, in dilutions of 10, 100, 1000 and 4000 ug / mL of both extracts and hydrocortisone (reference drug) where it was used NaCl 0.9% as dilution medium. The results for M. macrocarpa were 25.48% at a concentration of 10 ug / mL; 40.25% at 100 ug / mL; 62.64% at 1000 ug / mL and 64.46% at 4000 ug / mL; for J. spicigera 20.12% at a concentration of 10 ug / mL; 33.56% at 100 ug / mL; 52.28% at 1000 ug / mL and 55.22% at 4000 ug / mL; while Hydrocortisone 29.38% at a concentration of 10 ug / mL; 44.56% at 100 ug / mL; 74.53% at 1000 ug / mL and 82.65% at 4000 ug / mL, significant differences were found between the averages of protection percentages and concentrations in all the groups evaluated. The values of IC50 = 325.06 ug for M. macrocarpa bark, leaves of J. spicigera, an IC50 = 1201.91 ug and IC50 = 109.96 ug for Hydrocortisone, allowed to conclude that the latter is the one with the best anti-inflammatory activity in vitro.
El objetivo del presente trabajo de investigación fue determinar la actividad antiinflamatoria in vitro de extracto etanólico de corteza de Maytenus macrocarpa (Ruiz &Pav.) Briq. “chuchuhuasi” y hojas de Justicia spicigera Schltdl “insulina” por el método de estabilización de la membrana de glóbulos rojos, en concentraciones de 10, 100, 1000 y 4000 ug/mL de ambos extractos e hidrocortisona (fármaco de referencia) donde se utilizó ClNa 0,9% como medio de dilución. Los resultados para M. macrocarpa fueron de 25,48% a concentración 10 ug/mL; 40,25% a 100 ug/mL; 62,64% a 1000 ug/mL y 64,46% a 4000 ug/mL; para J. spicigera un 20,12% a concentración 10 ug/mL; 33,56% a 100 ug/mL; 52,28% a 1000 ug/mL y 55,22% a 4000 ug/mL; mientras que Hidrocortisona un 29,38% a concentración 10 ug/mL; 44,56% a 100 ug/mL; 74,53% a 1000 ug/mL y 82,65% a 4000 ug/mL. Se encontró diferencias significativas entre los promedios de porcentajes de protección y concentraciones en todos los grupos evaluados. Los valores de IC50=325,06 ug para corteza M. macrocarpa, hojas de J. spicigera un IC50=1201,91 ug e IC50=109,96 ug para Hidrocortisona, permitieron concluir que esta última es la de mejor actividad antiinflamatoria in vitro.
