Zusammenfassung
Aus den Früchten des Korianders (Coriandrum sativum L.) wurde das etherische Öl mittels flüssigen Kohlendioxid extrahiert. Die Modifizierung des J&W Hochdruckextrakteurs ermöglichte das Betrachten und die Kontrolle der Extraktion. Der Apparat konnte mit einer optimalen Menge von CO2 gefüllt werden, ohne den Extrakteur aufzumachen. Die Modifizierung ermöglichte entweder eine kontinuierliche oder eine siphonweise Funktion des Soxhletapparats zu wählen. Die CO2-Extrakte wurden gaschromatographisch mit Wasserdampfdestillaten und Lösungsmittelextrakten verglichen. Etwa 40 Verbindungen wurden massenspektrometrisch identifiziert.
Summary
The essential oil of coriander (Coriandrum sativum L.) fruits was extracted by liquid CO2. A J&W high pressure extraction apparatus was modified by providing means of visual control of the extraction. The apparatus could be filled with the optimum amount of extractant without disassembling the extractor. The modification made it possible to select the Soxhlet unit to function either continuously or in siphon cycles. The liquid CO2 extracts were compared with hydrodistillates and solvent extracts using capillary gas chromatography. Some 40 of the compounds were identified by mass spectrometry.
