Identificación y Evaluación de actividad antibacteriana contra Staphylococcus aureus de Metabolitos Secundarios a partir de Extractos de Eunicea sp y Plexaurella sp

Abstract

The purpose of this work is to identify metabolites with antibacterial activity from two species of octocorals of the genus Eunicea and Plexaurella collected in Providencia, Colombia. For the extraction of metabolites, two solvents (methanol and hexane) were used together with the use of a rotary evaporator and column fractionation. The identification of metabolites was carried out through the application of liquid chromatography coupled to mass spectrometry, where it was seen that the compounds found were mostly fatty acids. The antibacterial activity was carried out by the sensidisk method, using a chloramphenicol disc as a positive control, where finally inhibition of Staphylococcus aureus could be seen in the complete extract.
