Table 1 The chemical composition of Zingiber officinale essential oil from different geographical region Yield Rhizomes Components Location Ref 1.02 1.84% Fresh Dried -zingiberene (12.2%), geraniol (15.0%), neral (8.9%), -bisabolene (5.6%) and -sesquiphellandrene (6.4%) -zingiberene (28.1%), geraniol (9.0%), neral (5.3%), -bisaboleneThe composition of the essential oil of dried Nigerian The essential oil composition of dried Nigerian ginger (Zingiber officinale Roscoe) was determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The ginger was hydrodistilled; the oil yield was 2.4% and consisted of 64.4% sesquiterpene hydrocarbons, 6.6% carbonyl compounds, 5.6% alcohols, 2.4% monoterpene hydrocarbons and 1.6% esters.
