dc.description.abstractAnalysis of yield and composition profile of Melissa officinalis (Lemon balm) extract obtained by two-step CO2 extraction at high pressure was analyzed. The first or essential oil fraction, collected at 10 MPa and 40 degrees C, contained mostly the high volatile and aromatic compounds. The second fraction was consenquently extracted at 30 MPa using different temperature: 25 degrees C (higher pressure than critical pressure but at temperature below the critical; HPCP-CO2), 40 degrees C or 100 degrees C (supercritical CO2; SC-CO2). Obtained yield of essential oil fraction was 0.45% at 10 MPa, while depending on applied extraction temperature (HPCP-CO2 or SC-CO2), the yields of the second fractions collected at 30 MPa varied from 0.44% to 0.94%. Within the study, the content of active substances in obtained extracts was analyzed, too. For comparison with CO2 extracts (HPCP or SC) the yield and characterization of essential oil obtained by hydrodistillation was accomplished, as well. A significant difference was noted not only between the essential oil isolated by hydrodistillation and SC-CO2 extraction (40 degrees C, 10 MPa) but also between total extracts obtained by HPCP-CO2 and SC-CO2 extraction. The pseudo kinetic model was applied to define SC-CO2 extraction of Lemon balm to describe the relation between the yield of extraction and CO2 consumption. Antioxidant activity of obtained extracts was determined by free radical scavenging capacity (RSC) and significant correlation of antioxidant capacity and composition profile between obtained extracts was observed.en
