Chemical Composition and Antibacterial Activities of Essential Oils from Zingiber Spectabile Griff

The essential oils of the leaves and rhizomes of Zingiber spectabile Griff. were analyzed by capillary gas chromatography (GC) and GC-mass spectrometry (GC-MS) following the isolation by hydrodistillation. In total, 80 compounds were identified in its leaf and rhizome oils. Both oils were sesquiterp...

In total, 80 compounds were identified in its leaf and rhizome oils. Both oils were sesquiterpenic in nature but with distinctly different odors. The most abundant components in the leaf oil were beta-caryophyllene (21.3) and beta-elemene (12.5), whereas the rhizomes yielded an oil rich in zerumbone (59.1).
