| Summary: | Abstract Z. kleinii is an endemic species in Brazil. No reports of popular use, regarding its chemical composition or biological activities were reported to date. The study aimed to investigated the chemical composition of the essential oil of Zanthoxylum kleinii leaves and evaluate its antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis and methicillin-sensitive Staphylococcus aureus. The essential oil was extracted from fresh leaves by hydrodistillation method, using a Clevenger apparatus, having a yield of 0.12% (v/m) volume of essential oil in relation to the amount of plant material. Quantitative analysis was performed by GC-MS and the results showed that the essential oil contains 30 compounds. The major compounds are monoterpene hydrocarbons, including β-phellandrene (37.80%), α-pinene (13.32%) and myrcene (10.05%). The essential oil showed no antibacterial activity against the strains tested (E. coli, P. aeruginosa, E. faecalis and S. aureus). |
