Evaluación de la Actividad Antimicrobiana del Extracto Etanólico de Carrasquilla (Berberis halliii) sobre Echerichia coli ATCC No. 9637, Candida albicans ATCC No. 10231, Pseudomona aeruginosa ATCC No.. 27853, Staphysicoccus aureus ATCC No. 6538.

Abstract

The antimicrobial activity of the ethanolic extract of the Carrasquilla root (Berberis halliii) was evaluated. The studies were carried out in the Phytochemistry Laboratory and in the Microbiology Laboratory of the Faculty of Sciences of ESPOCH. To scientifically verify the antimicrobial activity of Berberis halliii by the Mitscher method. The root extract of Berberis halliii did not present activity against Escherichia coli ATCC 9637, Candida albicans ATCC 10231, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 6538 at concentrations of 10,000, 1000 and 100 (ug/mL), thus determining the antimicrobial activity using 40mg of ethanolic extract from the root of the plant. This study was carried out with the purpose of demonstrating whether or not there is activity to later carry out tests at different concentrations to dose the amount of active ingredient against the activity shown, the test was carried out against 4 ATCC strains: Escherichia coli ATCC 9637, Candida albicans ATCC 10231, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 6538. The ethanolic extract of the root of Berberis halliii did not present activity, therefore it could not be dosed at different concentrations and the study was terminated, since it shows that the information of its application against digestive problems and urinary infections is not true and cannot be used to combat problems of bacterial origin, therefore, it is recommended to carry out anti-inflammatory studies of this plant because in bibliographic data it says there is pharmacological activity and provide a good use of it.
