Abstract
En el estudio se aplicó un diseño experimental; la muestra vegetal estuvo representada por 500 gramos de hojas de guanábana, procedente de la localidad de Tactago, distrito de Cumba, Provincia de Utcubamba, departamento de Amazonas y la muestra microbiológica fue Escherichia coli ATCC 8739. Se realizaron ensayos de solubilidad con diferentes disolventes, análisis cualitativo del extracto para identificar los metabolitos y la actividad antimicrobiana del extracto hidroalcohólico de las hojas de Annona muricata L. “guanábana” a diferentes concentraciones frente a Escherichia coli ATCC 8739. Como resultado, se demostró ser soluble únicamente en solventes de naturaleza polar. Se concluye que el extracto hidroalcohólico de las hojas de guanábana no tuvo actividad antibacteriana frente a Escherichia coli ATCC 8739.
An experimental design was applied in the study; the plant sample was represented by 500 grams of soursop leaves from the locality of Tactago, district of Cumba, Utcubamba Province, department of Amazonas, and the microbiological sample was Escherichia coli ATCC 8739. Solubility tests were performed with different solvents, qualitative analysis of the extract to identify metabolites and the antimicrobial activity of the hydroalcoholic extract of Annona muricata L. "guanábana" leaves at different concentrations against Escherichia coli ATCC 8739. As a result, it was shown to be soluble only in solvents of polar nature. It is concluded that the hydroalcoholic extract of soursop leaves had no antibacterial activity against Escherichia coli ATCC 8739.
