Abstract: Litsea cubeba oil was obtained by steam distillation of fruit of Litsea cubeba (Lour.) Pers.and their components were identified by gas chromatography/mass spectrometry (GC-MS).Examination of inhibition effect of Litsea cubeba oil against three strains of bacterium isolated from daily chemical products was based on data of minimum inhibitory concentrations (MICs) determined by agar plane dish test.Meanwhile,the three strains of bacterium were appraised in accordance with 16S rRNA sequence analyses to determine their phylogenetic positions.Results showed that the main constituents of Litsea cubeba oil are D-limonene (w=26.51%),citral (w=11.94%) and verbenol (w=11.84%).All the three strains belong to gram-positive bacteria and are classified as Bacillus amyloliquefaciens subsp.plantarum GLM 50,Bacillus atrophaeus GLM 56 and Staphyococcus haemolyticus GLM 57 respectively.The MICs of Litsea cubeba oil against GLM 50,GLM 56 and GLM 57 are 0.045,0.09 and 0.18 g/L respectively.

Key words: Litsea cubeba oil, GC-MS, strain appraisal, antibacterial activity
