Abstract
The optimal conditions (40°С, 16 MPa, process duration of 30 min) for the extraction of Pelargonium graveolens L’Her essential oil using supercritical (SC) carbon dioxide are determined. GC-MS analysis shows higher concentrations of the target components (e.g., citronellol, geraniol) in the product in comparison to the oil obtained using a traditional method (steam distillation). Additional components, such as camphene, sabinene, and others are also present in the product obtained by the extraction with SC-CO2.
