Abstract

The extraction of the stinging nettle leaves was performed with 20 kg/h flow rate of supercritical CO2. The influence of the working parameters: pressure (140 bar, 210 bar and 350 bar), temperature (from 40 oC to 60 oC) on the quantity of extract and contents of chlorophyll a+b and β-carotene in it is determined. The biggest quantity of extract (4.48% in relation to the dry matter) with 0.88% contents of chlorophyll a+b and 0.50% β-carotene is obtained at 350 bar, 60 oC, 6h extraction time
