RHIZOME ESSENTIAL OIL COMPOSITION OF ZINGIBER CERNUUM AND ITS ANTI MICROBIAL ACTIVITYAbstract
Zingiber cernuum belongs to family Zingiberaceae is a perennial herb, also called as Curved stem ginger. The rhizomes of Zingiber cernuum is steam distilled and the composition of essential oil was studied. The essential oil obtained was yellow in colour and the yield was about 0.007%. The chemical profile of the oil was obtained from their GC-MS analysis. The major components present in the oil are trans-Caryophyllene, α-Humulene and δ-3-Carene. The antimicrobial activity of the essential oil was studied using disc diffusion method. The essential oil was tested against four pathogenic stains of gram positive and gram negative bacteria. The essential oil of Zingiber cernuum show considerable antibacterial activity. The oil was found to be active against both gram positive and gram negative bacteria. The anti bacterial activity is mainly due to the major components present in the oil or due to the synergistic effect of the major and minor components.
