Artículo Chemical properties and bactericidal activity of Rosmarinus officinalis and Origanum x majoricum(2015-10) Castañeda Antonio, María Dolores; Rivera, A.; Islas Rodríguez, E.; Portillo Reyes, R.; Muñoz Rojas, Jesús; Hernández Aldana, F.; Martínez Carrera, D.; Castañeda Antonio, María Dolores; 0000-0003-0350-3802; Muñoz Rojas, Jesús; 0000-0002-1151-9778"The aim of this study was to identify the chemical properties and bactericidal activity of Rosmarinus officinalis and Origanum x majoricum in relation to the compounds detected by gas chromatographic analysis. Proceeded to wash samples Rosmarinus officinalis and Origanum x majoricum and were referred to a mashing process for seven days at room temperature with ethanol, filtering the ethanol extracts. The extracts obtained were analyzed by a gas chromatography system equipped with a mass spectrometer. Staphylococcus aureus (ATCC 25923) was used to evaluate the activity antiomicrobial extracts of Rosmarinus officinalis and Origanum x majoricum by the Kirby-Bauer method modified and quantified with the software Image J. Rosmarinus officinalis were detected alcohol, terpene and cetone compounds noted for their abundance and absence of compounds thymol and carvacol. Origanum x majoricum were identified for a considerable percentage of alcohol, acids and esters compounds, highlighting the carvacol as one of the most abundant, and linolenic acid and paeonol was detected. Antimicrobial activity of Rosmarinus officinalis extracts showed greater antimicrobial activity against Staphylococcus aureus, with respect to extract Origanum x majoricum".
