Abstract
The fresh rhizomes of ginger (Zingiber officinale Roscoe) grown in Japan were extracted with n-hexane. The extract was fractionated into a hydrocarbon fraction (hexane fraction) and an oxygenated hydrocarbon fraction (CH2Cl2 fraction). The CH2Cl2 fraction was subjected to GC–Olfactometry (GC–O) and GC–mass spectrometry (MS) analyses. It was considered that monoterpenoids, linalool, 4-terpineol, isoborneol and borneol, as well as geranial and neral, might contribute to the characteristic odour of the Japanese fresh ginger. Each enantiomer of linalool, 4-terpineol, isoborneol and borneol were easily separated using the off-line multidimensional GC (MDGC) system. Simultaneously, the GC–O was carried out and the odour character of each enantiomer was confirmed. The thermal desorption cold trap injector (TCT) was used as a part of the off-line MDGC system. It was revealed that the TCT can be used not only for headspace analysis but also as a part of an MDGC system. Copyright © 2001 John Wiley & Sons, Ltd.
