    Description / Table of Contents: Zusammenfassung Der Aufbau eines Hochdruck-CO2-Extraktors wird beschrieben, der die Gewinnung etherischer Öle im Labormaßstab ermöglicht. Aus Thymian (Thymus vulgaris L.) wird das etherische Öl mittels CO2 extrahiert und die Inhaltsstoffe mit denen eines Wasserdampfdestillats und eines handelsüblichen Thymianöls verglichen. Bei der Analyse des etherischen Öls wurden gaschromatographisch und massenspektrometrisch etwa 50 Komponenten identifiziert.
    Notes: Summary The construction of a high pressure CO2 extractor is described, which allows the production of essential oils on a laboratory scale. The essential oil of thyme (Thymus vulgaris L.) was extracted with CO2 and the oil composition compared with that from a steam distillate and from a commercially available red thyme oil. By analysing the essential oils by means of gas chromatography and mass spectrometry about 50 components have been identified.

    Description / Table of Contents: Zusammenfassung Die etherischen Öle aus Rhizomen von Ingwer (Zingiber officinalis Rosc.) indischer und australischer Herkunft unterscheiden sich grundlegend in ihrer Zusammensetzung. Hauptbestandteile des aus Indischem Ingwer gewonnenen Öls sind die Sesquiterpenkohlenwasserstoffe ar-Curcumen, Zingiberen, α-Farnesen,β-Bisabolen undβ-Sesquiphel-landren. Hingegen besteht das etherische Öl des Australischen Ingwwes hauptsächlich aus den Monoterpenkohlenwasserstoffen Camphen und Phellandren und deren sauerstoffhaltigen Derivaten Neral, Geranial und 1,8-Cineol.
    Notes: Summary Essential oils from ginger rhizomes of different origins, such asZingiber officinalis Rosc. from India and Australia, differ remarkably in their terpenoid compositions. The main components of Indian ginger oil are the sesquiterpenoid hydrocarbons, arcurcumene, zingiberene, α-farnesene,β-bisabolene andβ-sesquiphellandrene. However, the essential oil from the Australian ginger consists mainly of the monoterpenoid hydrocarbons, camphene and phellandrene, and their oxygen-containing derivatives neral, geranial and 1,8-cineol.
