Abstract
El objetivo de la presente investigación fue evaluar la actividad
antibacteriana de un jarabe elaborado con extracto hidroalcohólico extraído de las
partes aéreas de Equisetum giganteum L. (cola de caballo). La especie vegetal fue
recolectada en el Distrito Huahuapuquio, Provincia de Cangallo del Departamento
Ayacucho, a unos a unos 2860 msnm. La extracción de los componentes bioactivos
se realizó mediante la selección, secado, molienda y preparación del extracto seco,
en el cual se encontró los siguientes metabolitos: compuestos fenólicos, alcaloides
y flavonoides. Mediante el método de tricloruro de aluminio se determinó la
concentración de flavonoides la cual fue de 1.30 mg de Quercetina/mL de extracto.
Se elaboró el jarabe con extracto hidroalcohólico de la especie Equisetum
giganteum L. en tres niveles de concentración, al 20%, 40% y 60%, según el
procedimiento del manual de técnicas de investigación de National Committee for
Clinical Laboratory Standars para evaluar su actividad antibacteriana. El desarrollo
de la evaluación microbiológica se realizó mediante el método de difusión en disco
(Kirby-Bauer), empleando el jarabe con extracto hidroalcohólico en sus tres niveles
de concentración frente a cepas clínicas de Staphylococcus aureus, el cual se
comparó con azitromicina 15 μg y amoxicilina base a 25 μg. Según los resultados
obtenidos, se comprobó que el jarabe con extracto hidroalcohólico de Equisetum
giganteum L. al 60 % posee mayor actividad antibacteriana frente a cepas clínicas
de Staphylococcus aureus. En conclusión, el jarabe con extracto hidroalcohólico de
la especie Equisetum giganteum L. (cola de caballo) presenta mayor efecto
antibacteriano desde las concentraciones de 40% y 60% sobre cepas clínicas de
Staphylococcus aureus cuya acción antibacteriana se relaciona con los compuestos
fenólicos, alcaloides y flavonoides encontrados en la especie.
The objective of the present investigation was to evaluate the antibacterial activity of a syrup made with hydroalcoholic extract extracted from the aerial parts of Equisetum giganteum L. (horsetail). The plant species was collected in the Huahuapuquio District, Cangallo Province of the Ayacucho Department, at about 2860 meters above sea level. The extraction of the bioactive components was carried out through the selection, drying, milling and preparation of the dry extract, in which the following metabolites were found: phenolic compounds, alkaloids and flavonoids. By means of the aluminum trichloride method, the concentration of flavonoids was determined, which was 1.30 mg of Quercetin / mL of extract. The syrup with hydroalcoholic extract of the species Equisetum giganteum L. was elaborated in three levels of concentration, at 20%, 40% and 60%, according to the procedure of the manual of investigation techniques of National Committee for Clinical Laboratory Standars to evaluate its antibacterial activity. The development of the microbiological evaluation was performed using the disk diffusion method (Kirby-Bauer), using the syrup with hydroalcoholic extract in its three concentration levels against clinical strains of Staphylococcus aureus, which was compared with azithromycin 15 μg and amoxicillin at 25 μg. According to the results obtained, it was verified that the syrup with hydroalcoholic extract of Equisetum giganteum L. to 60% has greater antibacterial activity against clinical strains of Staphylococcus aureus. In conclusion, the syrup with hydroalcoholic extract of the species Equisetum giganteum L. (horsetail) has a greater antibacterial effect from concentrations of 40% and 60% on clinical strains of Staphylococcus aureus whose antibacterial action is related to the phenolic compounds, alkaloids and flavonoids found in the species.
