Abstract

Laureliopsis philippiana (Looser) is native evergreen specie from Chile and Argentina used in traditional medicine. In this study, chemical composition as well as its in vitro antibacterial activity against Escherichia coli, Enterobacter aerogenes, Staphylococcus epidermidis and Staphylococcus aureus of essential oil from leaves of this species was determinated. Chemical analysis by GC-MS resulted in the identification of 19 compounds representing 98.8% of essential oil composition. Oxygenated monoterpenes; linalool (32.3%) and eucalyptol (37.4%) were the main constituents. To evaluate the antibacterial activity disc diffusion method and broth dilution method were used. The essential oil exhibited inhibitory activity against Gram (-) and Gram (+) bacteria, whereas similar activity to essential oil was showed for linalool against E. aerogenes and S. epidermidis whereas linalool alone, achieves an inhibitory effect against E. aerogenes and S. epidermidis comparable to the essential oil.
