Abstract: The leaf and rhizome essential oils composition of Zingiber officinale Roscoe was analyzed and compared by GC-FID and GC-MS. The analysis led to the identification of 85 constituents accounting for 90.08 % and 95.36 % of the total oil composition, respectively. The leaf essential oil of Z. officinale was mainly composed of monoterpenoids (45.49 %) and sesquiterpenoids (42.17 %); with β-caryophyllene (22.65 %), geranial (11.26 %), caryophyllene oxide (9.51 %), geraniol (8.29 %) and neral (7.44 %) as the major constituents while α-zingiberene (15.92 %), geranial (11.75 %), β-bisabolene (11.12 %), neral (9.25 %), β-phellandrene (7.73 %), and β-sesquiphellandrene (5.26 %) were the major constituemts of the rhizome oil of Z. officinale. Both the leaf and rhizome oils were tested for their antibacterial activity against six bacterial strains viz. Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus faecalis. The antioxidant activity of the rhizome oil of Z. officinale was also tested using a DPPH radical scavenging system.
