Sixty-five, thirty-four and seven compounds, accounting for 99.7%, 97.3% and 99.9% of the oils, were identified and the main components were. alpha-pinene (16.1%), 3-octanone (48.1%), and eicosane (28.6%), respectively. The essential oils were also tested against nine strains using a broth microdilution method and showed moderate antimicrobial activity with minimum inhibitory concentrations (MIC) ranging from 278.2 to 2225 mu g/mL. All the mosses essential oils showed good antituberculosis activity against Mycobacterium smegmatis with MIC of 278.2-312.0 mu g/mL.
