Title: | Investigation of cultivated lavender (Lavandula officinalis L.) extraction and its extracts | Authors: | Nadalin V. Lepojević Z. Mihailo Ristić Vladić, Jelena Nikolovski B. Adamović, Dragan |
Issue Date: | 28-Mar-2014 | Journal: | Chemical Industry and Chemical Engineering Quarterly | Abstract: | In this study essential oil content was determined in lavender flowers and leaves by hydrodistillation. Physical and chemical characteristics of the isolated oils were determined. By using CO2 in supercritical state, the extraction of lavender flowers was performed with a selected solvent flow under isothermal and isobaric conditions. Qualitative and quantitative analysis of the obtained essential oil and supercritical extracts (SFE) was carried out using gas chromatography in combination with mass spectrometry (GC/MS) and gas chromatography with flame ionisation detector (GC/FID). Also, the analysis of individual SFE extracts obtained during different extraction times was performed. The main components of the analysed samples were linalool, linalool acetate, lavandulol, caryophyllene oxide, lavandulyl acetate, terpinen-4-ol and others. Two proposed models were used for modelling the extraction system lavender flower - supercritical CO2 on the basis of experimental results obtained by examining the extraction kinetics of this system. The applied models fitted well with the experimental results. | URI: | https://open.uns.ac.rs/handle/123456789/7278 | ISSN: | 14519372 | DOI: | 10.2298/CICEQ120715103N |
