Sažetak
Lavandula angustifolia is good source of oxygenated monoterpenes containing coumarins as well, which are all soluble in supercritical CO2 (SC-CO2). The study objective is to investigate SC-CO2 extraction parameters on: the total yield ; GC- MS profile of the extracts ; relative content of oxygenated monoterpenes ; the amount of coumarin and herniarin ; and to determine optimal SC-CO2 extraction conditions by response surface methodology (RSM). SC-CO2 extraction was performed under different pressure, temperature and CO2 flow rate determined by Box-Behnken design (BBD). The plant material mass and the extraction time were kept constant. The extracts chemical profiles and relative content of oxygenated monoterpenes were determined by GC-MS. Coumarin and herniarin concentrations were dosed by HPLC. SC-CO2 extracts contained linalool (57.4-217.9 mg/100 g), camphor (10.6- 154.4 mg/100 g), borneol (6.2-99.9 mg/100 g), 1, 8- cineole (5.0-70.4 mg/100 g), linalyl acetate (86.1-267.9 mg/100 g), coumarin (0.95- 18.16 mg/100 g), and herniarin (0.95-13.63 mg/100 g). The interaction between the pressure and CO2 flow rate as well as between the temperature and CO2 flow rate showed statistically significant influence on the extraction yield. Applying BBD, the optimum extraction conditions for higher monoterpenes and lower coumarin content were at 10 MPa, 41°C and CO2 flow rate 2.3 kg/h, and at 30 MPa, 50°C and CO2 flow rate 3 kg/h for higher monoterpenes and coumarin content. SC-CO2 extraction is a viable technique for obtaining lavender extracts with desirable flavour components. The second-order model based on BBD predicts the results for SC- CO2 extraction quite satisfactorily.
