Evaluation of Supercritical Carbon Dioxide Extraction Efficiency for Pelargonium Graveolens LHer Essential Oil Production

Optimal conditions (40 °C, 16 MPa, process duration 30 min) for the extraction of Pelargonium graveolens LHer essential oil using supercritical (SC) carbon dioxide are determined. GC-MS analysis of the obtained product shows higher concentration of target components (e.g., citronellol, geraniol) in it compared to the oil obtained using a traditional method (steam distillation). Additional components, such as camphene, sabinene, etc., are also present in the product obtained via the extraction with SC-CO2.

Key words: Pelargonium graveolens, essential oil, supercritical fluid extraction
