Abstract
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. The main compounds were zingiberene (29.5%) and sesquiphellandrene (18.4%). A number of constituents not previously reported in ginger oil were identified. These include 2,6-dimethyl hepten-l-ol, α-gurjunene, linalool oxide, isovaler-aldehyde, 2-pentanone, cadinol, α- and γ-calacorene, eremophyllene, t-muurolol, α-himachallene, α-cubebene acetic acid, pinanol, α-santalene, geranyl propionate, geranoic acid, (E,E)-α-farnesene, n-methyl pyrrole and geranic acid.
