ABSTRACT:Curcuma singularis Gagnep., (Zingiberaceae) was found distributed in the Central Highlands of Vietnam and described as a new record for the country’s flora. From the fresh rhizomes of this plant, an essential oil was obtained by hydrodistillation with 0.31% yield (w/w). By GC-FID and GC-MS analysis, a total of 68 compounds were detected, of which 60 components accounting for 90.96% of the total oil were identified. Almost all of the components are mono- and sesquiterpenes (65 compounds, 98.57% total oil), most of them are oxygenated (51 compounds, 85.46% total oil). Major components are camphor (25.83%), germacrone (8.00%), caryophyllene oxide (4.48%), terpinen-4-ol (3.84%), and germacrone-4,5-epoxide (3.84%). In the antibacterial assays, the oil exhibited significant activity against the Gram positive bacteria Bacillus subtillis (MIC = 100 µg/ml) and the Gram negative bacteria Escherichia coli (MIC = 200 µg/ml).
