Volatile Constituents of Curcuma caesia Roxb. Rhizome from North India

摘要

The volatile constituents of Curcuma caesia Roxb. rhizome were obtained by hydro-distillation and investigated using gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Furthermore, the antibacterial activity of crude oil has been assessed by agar well diffusion method against five bacterial pathogens causing respiratory diseases. Forty-eight constituents representing 99.28% of the total oil were identified. The major constituents were cycloisolongifolene, 8,9-dehydro-9-formyl (11.67%), camphor (6.05%), eucalyptol (5.96), beta-germacrene (5.23%), 2,4,6-cycloheptatrien-1-one, 2-hydroxy-5-(3-methyl-2-butenyl)-4-(1-methylethenyl) (5.18%) and isoborneol (5.05%), while others were present in relatively small amounts. The antibacterial assay showed significant results against selected bacterial strains.
